+
+``tqdm`` derives from the Arabic word *taqaddum* (تقدّم) which can mean "progress,"
+and is an abbreviation for "I love you so much" in Spanish (*te quiero demasiado*).
+
+Instantly make your loops show a smart progress meter - just wrap any
+iterable with ``tqdm(iterable)``, and you're done!
+
+.. code:: python
+
+    from tqdm import tqdm
+    for i in tqdm(range(10000)):
+        ...
+
+``76%|████████████████████████        | 7568/10000 [00:33<00:10, 229.00it/s]``
+
+``trange(N)`` can also be used as a convenient shortcut for
+``tqdm(range(N))``.
+
+|Screenshot|
+    |Video| |Slides| |Merch|
+
+It can also be executed as a module with pipes:
+
+.. code:: sh
+
+    $ seq 9999999 | tqdm --bytes | wc -l
+    75.2MB [00:00, 217MB/s]
+    9999999
+
+    $ tar -zcf - docs/ | tqdm --bytes --total `du -sb docs/ | cut -f1` \
+        > backup.tgz
+     32%|██████████▍                      | 8.89G/27.9G [00:42<01:31, 223MB/s]
+
+Overhead is low -- about 60ns per iteration (80ns with ``tqdm.gui``), and is
+unit tested against performance regression.
+By comparison, the well-established
+`ProgressBar <https://github.com/niltonvolpato/python-progressbar>`__ has
+an 800ns/iter overhead.
+
+In addition to its low overhead, ``tqdm`` uses smart algorithms to predict
+the remaining time and to skip unnecessary iteration displays, which allows
+for a negligible overhead in most cases.
+
+``tqdm`` works on any platform
+(Linux, Windows, Mac, FreeBSD, NetBSD, Solaris/SunOS),
+in any console or in a GUI, and is also friendly with IPython/Jupyter notebooks.
+
+``tqdm`` does not require any dependencies (not even ``curses``!), just
+Python and an environment supporting ``carriage return \r`` and
+``line feed \n`` control characters.

+Changelog
+---------
+
+The list of all changes is available either on GitHub's Releases:
+|GitHub-Status|, on the
+`wiki <https://github.com/tqdm/tqdm/wiki/Releases>`__, or on the
+`website <https://tqdm.github.io/releases>`__.
+
+
+Usage
+-----
+
+``tqdm`` is very versatile and can be used in a number of ways.
+The three main ones are given below.
+
+Iterable-based
+~~~~~~~~~~~~~~
+
+Wrap ``tqdm()`` around any iterable:
+
+.. code:: python
+
+    from tqdm import tqdm
+    from time import sleep
+
+    text = ""
+    for char in tqdm(["a", "b", "c", "d"]):
+        sleep(0.25)
+        text = text + char
+
+``trange(i)`` is a special optimised instance of ``tqdm(range(i))``:
+
+.. code:: python
+
+    from tqdm import trange
+
+    for i in trange(100):
+        sleep(0.01)
+
+Instantiation outside of the loop allows for manual control over ``tqdm()``:
+
+.. code:: python
+
+    pbar = tqdm(["a", "b", "c", "d"])
+    for char in pbar:
+        sleep(0.25)
+        pbar.set_description("Processing %s" % char)
+
+Manual
+~~~~~~
+
+Manual control of ``tqdm()`` updates using a ``with`` statement:
+
+.. code:: python
+
+    with tqdm(total=100) as pbar:
+        for i in range(10):
+            sleep(0.1)
+            pbar.update(10)
+
+If the optional variable ``total`` (or an iterable with ``len()``) is
+provided, predictive stats are displayed.
+
+``with`` is also optional (you can just assign ``tqdm()`` to a variable,
+but in this case don't forget to ``del`` or ``close()`` at the end:
+
+.. code:: python
+
+    pbar = tqdm(total=100)
+    for i in range(10):
+        sleep(0.1)
+        pbar.update(10)
+    pbar.close()
+
+Module
+~~~~~~
+
+Perhaps the most wonderful use of ``tqdm`` is in a script or on the command
+line. Simply inserting ``tqdm`` (or ``python -m tqdm``) between pipes will pass
+through all ``stdin`` to ``stdout`` while printing progress to ``stderr``.
+
+The example below demonstrate counting the number of lines in all Python files
+in the current directory, with timing information included.
+
+.. code:: sh
+
+    $ time find . -name '*.py' -type f -exec cat \{} \; | wc -l
+    857365
+
+    real    0m3.458s
+    user    0m0.274s
+    sys     0m3.325s
+
+    $ time find . -name '*.py' -type f -exec cat \{} \; | tqdm | wc -l
+    857366it [00:03, 246471.31it/s]
+    857365
+
+    real    0m3.585s
+    user    0m0.862s
+    sys     0m3.358s
+
+Note that the usual arguments for ``tqdm`` can also be specified.
+
+.. code:: sh
+
+    $ find . -name '*.py' -type f -exec cat \{} \; |
+        tqdm --unit loc --unit_scale --total 857366 >> /dev/null
+    100%|█████████████████████████████████| 857K/857K [00:04<00:00, 246Kloc/s]
+
+Backing up a large directory?
+
+.. code:: sh
+
+    $ tar -zcf - docs/ | tqdm --bytes --total `du -sb docs/ | cut -f1` \
+      > backup.tgz
+     44%|██████████████▊                   | 153M/352M [00:14<00:18, 11.0MB/s]
+
+This can be beautified further:
+
+.. code:: sh
+
+    $ BYTES=$(du -sb docs/ | cut -f1)
+    $ tar -cf - docs/ \
+      | tqdm --bytes --total "$BYTES" --desc Processing | gzip \
+      | tqdm --bytes --total "$BYTES" --desc Compressed --position 1 \
+      > ~/backup.tgz
+    Processing: 100%|██████████████████████| 352M/352M [00:14<00:00, 30.2MB/s]
+    Compressed:  42%|█████████▎            | 148M/352M [00:14<00:19, 10.9MB/s]
+
+Or done on a file level using 7-zip:
+
+.. code:: sh
+
+    $ 7z a -bd -r backup.7z docs/ | grep Compressing \
+      | tqdm --total $(find docs/ -type f | wc -l) --unit files \
+      | grep -v Compressing
+    100%|██████████████████████████▉| 15327/15327 [01:00<00:00, 712.96files/s]
+
+Pre-existing CLI programs already outputting basic progress information will
+benefit from ``tqdm``'s ``--update`` and ``--update_to`` flags:
+
+.. code:: sh
+
+    $ seq 3 0.1 5 | tqdm --total 5 --update_to --null
+    100%|████████████████████████████████████| 5.0/5 [00:00<00:00, 9673.21it/s]
+    $ seq 10 | tqdm --update --null  # 1 + 2 + ... + 10 = 55 iterations
+    55it [00:00, 90006.52it/s]
+
+FAQ and Known Issues
+--------------------
+
+|GitHub-Issues|
+
+The most common issues relate to excessive output on multiple lines, instead
+of a neat one-line progress bar.
+
+- Consoles in general: require support for carriage return (``CR``, ``\r``).
+
+  * Some cloud logging consoles which don't support ``\r`` properly
+    (`cloudwatch <https://github.com/tqdm/tqdm/issues/966>`__,
+    `K8s <https://github.com/tqdm/tqdm/issues/1319>`__) may benefit from
+    ``export TQDM_POSITION=-1``.
+
+- Nested progress bars:
+
+  * Consoles in general: require support for moving cursors up to the
+    previous line. For example,
+    `IDLE <https://github.com/tqdm/tqdm/issues/191#issuecomment-230168030>`__,
+    `ConEmu <https://github.com/tqdm/tqdm/issues/254>`__ and
+    `PyCharm <https://github.com/tqdm/tqdm/issues/203>`__ (also
+    `here <https://github.com/tqdm/tqdm/issues/208>`__,
+    `here <https://github.com/tqdm/tqdm/issues/307>`__, and
+    `here <https://github.com/tqdm/tqdm/issues/454#issuecomment-335416815>`__)
+    lack full support.
+  * Windows: additionally may require the Python module ``colorama``
+    to ensure nested bars stay within their respective lines.
+
+- Unicode:
+
+  * Environments which report that they support unicode will have solid smooth
+    progress bars. The fallback is an ``ascii``-only bar.
+  * Windows consoles often only partially support unicode and thus
+    `often require explicit ascii=True <https://github.com/tqdm/tqdm/issues/454#issuecomment-335416815>`__
+    (also `here <https://github.com/tqdm/tqdm/issues/499>`__). This is due to
+    either normal-width unicode characters being incorrectly displayed as
+    "wide", or some unicode characters not rendering.
+
+- Wrapping generators:
+
+  * Generator wrapper functions tend to hide the length of iterables.
+    ``tqdm`` does not.
+  * Replace ``tqdm(enumerate(...))`` with ``enumerate(tqdm(...))`` or
+    ``tqdm(enumerate(x), total=len(x), ...)``.
+    The same applies to ``numpy.ndenumerate``.
+  * Replace ``tqdm(zip(a, b))`` with ``zip(tqdm(a), b)`` or even
+    ``zip(tqdm(a), tqdm(b))``.
+  * The same applies to ``itertools``.
+  * Some useful convenience functions can be found under ``tqdm.contrib``.
+
+- `No intermediate output in docker-compose <https://github.com/tqdm/tqdm/issues/771>`__:
+  use ``docker-compose run`` instead of ``docker-compose up`` and ``tty: true``.
+
+- Overriding defaults via environment variables:
+  e.g. in CI/cloud jobs, ``export TQDM_MININTERVAL=5`` to avoid log spam.
+  This override logic is handled by the ``tqdm.utils.envwrap`` decorator
+  (useful independent of ``tqdm``).
+
+If you come across any other difficulties, browse and file |GitHub-Issues|.

+
+Parameters
+~~~~~~~~~~
+
+* iterable  : iterable, optional  
+    Iterable to decorate with a progress bar.
+    Leave blank to manually manage the updates.
+* desc  : str, optional  
+    Prefix for the progress bar.
+* total  : int or float, optional  
+    The number of expected iterations. If unspecified,
+    len(iterable) is used if possible. If float("inf") or as a last
+    resort, only basic progress statistics are displayed
+    (no ETA, no progress bar).
+    If ``gui`` is True and this parameter needs subsequent updating,
+    specify an initial arbitrary large positive number,
+    e.g. 9e9.
+* leave  : bool, optional  
+    If [default: True], keeps all traces of the progress bar
+    upon termination of iteration.
+    If ``None``, will leave only if ``position`` is ``0``.
+* file  : ``io.TextIOWrapper`` or ``io.StringIO``, optional  
+    Specifies where to output the progress messages
+    (default: sys.stderr). Uses ``file.write(str)`` and ``file.flush()``
+    methods.  For encoding, see ``write_bytes``.
+* ncols  : int, optional  
+    The width of the entire output message. If specified,
+    dynamically resizes the progress bar to stay within this bound.
+    If unspecified, attempts to use environment width. The
+    fallback is a meter width of 10 and no limit for the counter and
+    statistics. If 0, will not print any meter (only stats).
+* mininterval  : float, optional  
+    Minimum progress display update interval [default: 0.1] seconds.
+* maxinterval  : float, optional  
+    Maximum progress display update interval [default: 10] seconds.
+    Automatically adjusts ``miniters`` to correspond to ``mininterval``
+    after long display update lag. Only works if ``dynamic_miniters``
+    or monitor thread is enabled.
+* miniters  : int or float, optional  
+    Minimum progress display update interval, in iterations.
+    If 0 and ``dynamic_miniters``, will automatically adjust to equal
+    ``mininterval`` (more CPU efficient, good for tight loops).
+    If > 0, will skip display of specified number of iterations.
+    Tweak this and ``mininterval`` to get very efficient loops.
+    If your progress is erratic with both fast and slow iterations
+    (network, skipping items, etc) you should set miniters=1.
+* ascii  : bool or str, optional  
+    If unspecified or False, use unicode (smooth blocks) to fill
+    the meter. The fallback is to use ASCII characters " 123456789#".
+* disable  : bool, optional  
+    Whether to disable the entire progress bar wrapper
+    [default: False]. If set to None, disable on non-TTY.
+* unit  : str, optional  
+    String that will be used to define the unit of each iteration
+    [default: it].
+* unit_scale  : bool or int or float, optional  
+    If 1 or True, the number of iterations will be reduced/scaled
+    automatically and a metric prefix following the
+    International System of Units standard will be added
+    (kilo, mega, etc.) [default: False]. If any other non-zero
+    number, will scale ``total`` and ``n``.
+* dynamic_ncols  : bool, optional  
+    If set, constantly alters ``ncols`` and ``nrows`` to the
+    environment (allowing for window resizes) [default: False].
+* smoothing  : float, optional  
+    Exponential moving average smoothing factor for speed estimates
+    (ignored in GUI mode). Ranges from 0 (average speed) to 1
+    (current/instantaneous speed) [default: 0.3].
+* bar_format  : str, optional  
+    Specify a custom bar string formatting. May impact performance.
+    [default: '{l_bar}{bar}{r_bar}'], where
+    l_bar='{desc}: {percentage:3.0f}%|' and
+    r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, '
+    '{rate_fmt}{postfix}]'
+    Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt,
+    percentage, elapsed, elapsed_s, ncols, nrows, desc, unit,
+    rate, rate_fmt, rate_noinv, rate_noinv_fmt,
+    rate_inv, rate_inv_fmt, postfix, unit_divisor,
+    remaining, remaining_s, eta.
+    Note that a trailing ": " is automatically removed after {desc}
+    if the latter is empty.
+* initial  : int or float, optional  
+    The initial counter value. Useful when restarting a progress
+    bar [default: 0]. If using float, consider specifying ``{n:.3f}``
+    or similar in ``bar_format``, or specifying ``unit_scale``.
+* position  : int, optional  
+    Specify the line offset to print this bar (starting from 0)
+    Automatic if unspecified.
+    Useful to manage multiple bars at once (eg, from threads).
+* postfix  : dict or ``*``, optional  
+    Specify additional stats to display at the end of the bar.
+    Calls ``set_postfix(**postfix)`` if possible (dict).
+* unit_divisor  : float, optional  
+    [default: 1000], ignored unless ``unit_scale`` is True.
+* write_bytes  : bool, optional  
+    Whether to write bytes. If (default: False) will write unicode.
+* lock_args  : tuple, optional  
+    Passed to ``refresh`` for intermediate output
+    (initialisation, iterating, and updating).
+* nrows  : int, optional  
+    The screen height. If specified, hides nested bars outside this
+    bound. If unspecified, attempts to use environment height.
+    The fallback is 20.
+* colour  : str, optional  
+    Bar colour (e.g. 'green', '#00ff00').
+* delay  : float, optional  
+    Don't display until [default: 0] seconds have elapsed.
+
+Extra CLI Options
+~~~~~~~~~~~~~~~~~
+
+* delim  : chr, optional  
+    Delimiting character [default: '\n']. Use '\0' for null.
+    N.B.: on Windows systems, Python converts '\n' to '\r\n'.
+* buf_size  : int, optional  
+    String buffer size in bytes [default: 256]
+    used when ``delim`` is specified.
+* bytes  : bool, optional  
+    If true, will count bytes, ignore ``delim``, and default
+    ``unit_scale`` to True, ``unit_divisor`` to 1024, and ``unit`` to 'B'.
+* tee  : bool, optional  
+    If true, passes ``stdin`` to both ``stderr`` and ``stdout``.
+* update  : bool, optional  
+    If true, will treat input as newly elapsed iterations,
+    i.e. numbers to pass to ``update()``. Note that this is slow

+
+Description and additional stats
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Custom information can be displayed and updated dynamically on ``tqdm`` bars
+with the ``desc`` and ``postfix`` arguments:
+
+.. code:: python
+
+    from tqdm import tqdm, trange
+    from random import random, randint
+    from time import sleep
+
+    with trange(10) as t:
+        for i in t:
+            # Description will be displayed on the left
+            t.set_description('GEN %i' % i)
+            # Postfix will be displayed on the right,
+            # formatted automatically based on argument's datatype
+            t.set_postfix(loss=random(), gen=randint(1,999), str='h',
+                          lst=[1, 2])
+            sleep(0.1)
+
+    with tqdm(total=10, bar_format="{postfix[0]} {postfix[1][value]:>8.2g}",
+              postfix=["Batch", {"value": 0}]) as t:
+        for i in range(10):
+            sleep(0.1)
+            t.postfix[1]["value"] = i / 2
+            t.update()
+
+Points to remember when using ``{postfix[...]}`` in the ``bar_format`` string:
+
+- ``postfix`` also needs to be passed as an initial argument in a compatible
+  format, and
+- ``postfix`` will be auto-converted to a string if it is a ``dict``-like
+  object. To prevent this behaviour, insert an extra item into the dictionary
+  where the key is not a string.
+
+Additional ``bar_format`` parameters may also be defined by overriding
+``format_dict``, and the bar itself may be modified using ``ascii``:
+
+.. code:: python
+
+    from tqdm import tqdm
+    class TqdmExtraFormat(tqdm):
+        """Provides a `total_time` format parameter"""
+        @property
+        def format_dict(self):
+            d = super().format_dict
+            total_time = d["elapsed"] * (d["total"] or 0) / max(d["n"], 1)
+            d.update(total_time=self.format_interval(total_time) + " in total")
+            return d
+
+    for i in TqdmExtraFormat(
+          range(9), ascii=" .oO0",
+          bar_format="{total_time}: {percentage:.0f}%|{bar}{r_bar}"):
+        if i == 4:
+            break
+
+.. code::
+
+    00:00 in total: 44%|0000.     | 4/9 [00:00<00:00, 962.93it/s]
+
+Note that ``{bar}`` also supports a format specifier ``[width][type]``.
+
+- ``width``
+
+  * unspecified (default): automatic to fill ``ncols``
+  * ``int >= 0``: fixed width overriding ``ncols`` logic
+  * ``int < 0``: subtract from the automatic default
+
+- ``type``
+
+  * ``a``: ascii (``ascii=True`` override)
+  * ``u``: unicode (``ascii=False`` override)
+  * ``b``: blank (``ascii="  "`` override)
+
+This means a fixed bar with right-justified text may be created by using:
+``bar_format="{l_bar}{bar:10}|{bar:-10b}right-justified"``
+
+Nested progress bars
+~~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` supports nested progress bars. Here's an example:
+
+.. code:: python
+
+    from tqdm.auto import trange
+    from time import sleep
+
+    for i in trange(4, desc='1st loop'):
+        for j in trange(5, desc='2nd loop'):
+            for k in trange(50, desc='3rd loop', leave=False):
+                sleep(0.01)
+
+For manual control over positioning (e.g. for multi-processing use),
+you may specify ``position=n`` where ``n=0`` for the outermost bar,
+``n=1`` for the next, and so on.
+However, it's best to check if ``tqdm`` can work without manual ``position``
+first.
+
+.. code:: python
+
+    from time import sleep
+    from tqdm import trange, tqdm
+    from multiprocessing import Pool, RLock, freeze_support
+
+    L = list(range(9))
+
+    def progresser(n):
+        interval = 0.001 / (n + 2)
+        total = 5000
+        text = f"#{n}, est. {interval * total:<04.2}s"
+        for _ in trange(total, desc=text, position=n):
+            sleep(interval)
+
+    if __name__ == '__main__':
+        freeze_support()  # for Windows support
+        tqdm.set_lock(RLock())  # for managing output contention
+        p = Pool(initializer=tqdm.set_lock, initargs=(tqdm.get_lock(),))
+        p.map(progresser, L)
+
+Note that in Python 3, ``tqdm.write`` is thread-safe:
+
+.. code:: python
+
+    from time import sleep
+    from tqdm import tqdm, trange
+    from concurrent.futures import ThreadPoolExecutor
+
+    L = list(range(9))
+
+    def progresser(n):
+        interval = 0.001 / (n + 2)
+        total = 5000
+        text = f"#{n}, est. {interval * total:<04.2}s"
+        for _ in trange(total, desc=text):
+            sleep(interval)
+        if n == 6:
+            tqdm.write("n == 6 completed.")
+            tqdm.write("`tqdm.write()` is thread-safe in py3!")
+
+    if __name__ == '__main__':
+        with ThreadPoolExecutor() as p:
+            p.map(progresser, L)
+
+Hooks and callbacks
+~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` can easily support callbacks/hooks and manual updates.
+Here's an example with ``urllib``:
+
+**``urllib.urlretrieve`` documentation**
+
+    | [...]
+    | If present, the hook function will be called once
+    | on establishment of the network connection and once after each block read
+    | thereafter. The hook will be passed three arguments; a count of blocks
+    | transferred so far, a block size in bytes, and the total size of the file.
+    | [...]
+
+.. code:: python
+
+    import urllib, os
+    from tqdm import tqdm
+    urllib = getattr(urllib, 'request', urllib)
+
+    class TqdmUpTo(tqdm):
+        """Provides `update_to(n)` which uses `tqdm.update(delta_n)`."""
+        def update_to(self, b=1, bsize=1, tsize=None):
+            """
+            b  : int, optional
+                Number of blocks transferred so far [default: 1].
+            bsize  : int, optional
+                Size of each block (in tqdm units) [default: 1].
+            tsize  : int, optional
+                Total size (in tqdm units). If [default: None] remains unchanged.
+            """
+            if tsize is not None:
+                self.total = tsize
+            return self.update(b * bsize - self.n)  # also sets self.n = b * bsize
+
+    eg_link = "https://cgi.cdcl.ml/matryoshka.zip"
+    with TqdmUpTo(unit='B', unit_scale=True, unit_divisor=1024, miniters=1,
+                  desc=eg_link.split('/')[-1]) as t:  # all optional kwargs
+        urllib.urlretrieve(eg_link, filename=os.devnull,
+                           reporthook=t.update_to, data=None)
+        t.total = t.n
+
+Inspired by `twine#242 <https://github.com/pypa/twine/pull/242>`__.
+Functional alternative in
+`examples/tqdm_wget.py <https://github.com/tqdm/tqdm/blob/master/examples/tqdm_wget.py>`__.
+
+It is recommend to use ``miniters=1`` whenever there is potentially
+large differences in iteration speed (e.g. downloading a file over
+a patchy connection).
+
+**Wrapping read/write methods**
+
+To measure throughput through a file-like object's ``read`` or ``write``
+methods, use ``CallbackIOWrapper``:
+
+.. code:: python
+
+    from tqdm.auto import tqdm
+    from tqdm.utils import CallbackIOWrapper
+
+    with tqdm(total=file_obj.size,
+              unit='B', unit_scale=True, unit_divisor=1024) as t:
+        fobj = CallbackIOWrapper(t.update, file_obj, "read")
+        while True:
+            chunk = fobj.read(chunk_size)
+            if not chunk:
+                break
+        t.reset()
+        # ... continue to use `t` for something else
+
+Alternatively, use the even simpler ``wrapattr`` convenience function,
+which would condense both the ``urllib`` and ``CallbackIOWrapper`` examples
+down to:
+
+.. code:: python
+
+    import urllib, os
+    from tqdm import tqdm
+
+    eg_link = "https://cgi.cdcl.ml/matryoshka.zip"
+    response = getattr(urllib, 'request', urllib).urlopen(eg_link)
+    with tqdm.wrapattr(open(os.devnull, "wb"), "write",
+                       miniters=1, desc=eg_link.split('/')[-1],
+                       total=getattr(response, 'length', None)) as fout:
+        for chunk in response:
+            fout.write(chunk)
+
+The ``requests`` equivalent is nearly identical:
+
+.. code:: python
+
+    import requests, os
+    from tqdm import tqdm
+
+    eg_link = "https://cgi.cdcl.ml/matryoshka.zip"
+    response = requests.get(eg_link, stream=True)
+    with tqdm.wrapattr(open(os.devnull, "wb"), "write",
+                       miniters=1, desc=eg_link.split('/')[-1],
+                       total=int(response.headers.get('content-length', 0))) as fout:
+        for chunk in response.iter_content(chunk_size=4096):
+            fout.write(chunk)
+
+**Custom callback**
+
+``tqdm`` is known for intelligently skipping unnecessary displays. To make a
+custom callback take advantage of this, simply use the return value of
+``update()``. This is set to ``True`` if a ``display()`` was triggered.
+
+.. code:: python
+
+    from tqdm.auto import tqdm as std_tqdm
+
+    def external_callback(*args, **kwargs):
+        ...
+
+    class TqdmExt(std_tqdm):
+        def update(self, n=1):
+            displayed = super().update(n)
+            if displayed:
+                external_callback(**self.format_dict)
+            return displayed
+
+``asyncio``
+~~~~~~~~~~~
+
+Note that ``break`` isn't currently caught by asynchronous iterators.
+This means that ``tqdm`` cannot clean up after itself in this case:
+
+.. code:: python
+
+    from tqdm.asyncio import tqdm
+
+    async for i in tqdm(range(9)):
+        if i == 2:
+            break
+
+Instead, either call ``pbar.close()`` manually or use the context manager syntax:
+
+.. code:: python
+
+    from tqdm.asyncio import tqdm
+
+    with tqdm(range(9)) as pbar:
+        async for i in pbar:
+            if i == 2:
+                break
+
+Pandas Integration
+~~~~~~~~~~~~~~~~~~
+
+Due to popular demand we've added support for ``pandas`` -- here's an example
+for ``DataFrame.progress_apply`` and ``DataFrameGroupBy.progress_apply``:
+
+.. code:: python
+
+    import pandas as pd
+    import numpy as np
+    from tqdm import tqdm
+
+    df = pd.DataFrame(np.random.randint(0, 100, (100000, 6)))
+
+    # Register `pandas.progress_apply` and `pandas.Series.map_apply` with `tqdm`
+    # (can use `tqdm.gui.tqdm`, `tqdm.notebook.tqdm`, optional kwargs, etc.)
+    tqdm.pandas(desc="my bar!")
+
+    # Now you can use `progress_apply` instead of `apply`
+    # and `progress_map` instead of `map`
+    df.progress_apply(lambda x: x**2)
+    # can also groupby:
+    # df.groupby(0).progress_apply(lambda x: x**2)
+
+In case you're interested in how this works (and how to modify it for your
+own callbacks), see the
+`examples <https://github.com/tqdm/tqdm/tree/master/examples>`__
+folder or import the module and run ``help()``.
+
+Keras Integration
+~~~~~~~~~~~~~~~~~
+
+A ``keras`` callback is also available:
+
+.. code:: python
+
+    from tqdm.keras import TqdmCallback
+
+    ...
+
+    model.fit(..., verbose=0, callbacks=[TqdmCallback()])
+
+Dask Integration
+~~~~~~~~~~~~~~~~
+
+A ``dask`` callback is also available:
+
+.. code:: python
+
+    from tqdm.dask import TqdmCallback
+
+    with TqdmCallback(desc="compute"):
+        ...
+        arr.compute()
+
+    # or use callback globally
+    cb = TqdmCallback(desc="global")
+    cb.register()
+    arr.compute()
+
+IPython/Jupyter Integration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+IPython/Jupyter is supported via the ``tqdm.notebook`` submodule:
+
+.. code:: python
+
+    from tqdm.notebook import trange, tqdm
+    from time import sleep
+
+    for i in trange(3, desc='1st loop'):
+        for j in tqdm(range(100), desc='2nd loop'):
+            sleep(0.01)
+
+In addition to ``tqdm`` features, the submodule provides a native Jupyter
+widget (compatible with IPython v1-v4 and Jupyter), fully working nested bars
+and colour hints (blue: normal, green: completed, red: error/interrupt,
+light blue: no ETA); as demonstrated below.
+
+|Screenshot-Jupyter1|
+|Screenshot-Jupyter2|
+|Screenshot-Jupyter3|
+
+The ``notebook`` version supports percentage or pixels for overall width
+(e.g.: ``ncols='100%'`` or ``ncols='480px'``).
+
+It is also possible to let ``tqdm`` automatically choose between
+console or notebook versions by using the ``autonotebook`` submodule:
+
+.. code:: python
+
+    from tqdm.autonotebook import tqdm
+    tqdm.pandas()
+
+Note that this will issue a ``TqdmExperimentalWarning`` if run in a notebook
+since it is not meant to be possible to distinguish between ``jupyter notebook``
+and ``jupyter console``. Use ``auto`` instead of ``autonotebook`` to suppress
+this warning.
+
+Note that notebooks will display the bar in the cell where it was created.
+This may be a different cell from the one where it is used.
+If this is not desired, either
+
+- delay the creation of the bar to the cell where it must be displayed, or
+- create the bar with ``display=False``, and in a later cell call
+  ``display(bar.container)``:
+
+.. code:: python
+
+    from tqdm.notebook import tqdm
+    pbar = tqdm(..., display=False)
+
+.. code:: python
+
+    # different cell
+    display(pbar.container)
+
+The ``keras`` callback has a ``display()`` method which can be used likewise:
+
+.. code:: python
+
+    from tqdm.keras import TqdmCallback
+    cbk = TqdmCallback(display=False)
+
+.. code:: python
+
+    # different cell
+    cbk.display()
+    model.fit(..., verbose=0, callbacks=[cbk])
+
+Another possibility is to have a single bar (near the top of the notebook)
+which is constantly re-used (using ``reset()`` rather than ``close()``).
+For this reason, the notebook version (unlike the CLI version) does not
+automatically call ``close()`` upon ``Exception``.
+
+.. code:: python
+
+    from tqdm.notebook import tqdm
+    pbar = tqdm()
+
+.. code:: python
+
+    # different cell
+    iterable = range(100)
+    pbar.reset(total=len(iterable))  # initialise with new `total`
+    for i in iterable:
+        pbar.update()
+    pbar.refresh()  # force print final status but don't `close()`
+
+Custom Integration
+~~~~~~~~~~~~~~~~~~
+
+To change the default arguments (such as making ``dynamic_ncols=True``),
+simply use built-in Python magic:
+
+.. code:: python
+
+    from functools import partial
+    from tqdm import tqdm as std_tqdm
+    tqdm = partial(std_tqdm, dynamic_ncols=True)
+
+For further customisation,
+``tqdm`` may be inherited from to create custom callbacks (as with the
+``TqdmUpTo`` example `above <#hooks-and-callbacks>`__) or for custom frontends
+(e.g. GUIs such as notebook or plotting packages). In the latter case:
+
+1. ``def __init__()`` to call ``super().__init__(..., gui=True)`` to disable
+   terminal ``status_printer`` creation.
+2. Redefine: ``close()``, ``clear()``, ``display()``.
+
+Consider overloading ``display()`` to use e.g.
+``self.frontend(**self.format_dict)`` instead of ``self.sp(repr(self))``.
+
+Some submodule examples of inheritance:

+
+Dynamic Monitor/Meter
+~~~~~~~~~~~~~~~~~~~~~
+
+You can use a ``tqdm`` as a meter which is not monotonically increasing.
+This could be because ``n`` decreases (e.g. a CPU usage monitor) or ``total``
+changes.
+
+One example would be recursively searching for files. The ``total`` is the
+number of objects found so far, while ``n`` is the number of those objects which
+are files (rather than folders):
+
+.. code:: python
+
+    from tqdm import tqdm
+    import os.path
+
+    def find_files_recursively(path, show_progress=True):
+        files = []
+        # total=1 assumes `path` is a file
+        t = tqdm(total=1, unit="file", disable=not show_progress)
+        if not os.path.exists(path):
+            raise IOError("Cannot find:" + path)
+
+        def append_found_file(f):
+            files.append(f)
+            t.update()
+
+        def list_found_dir(path):
+            """returns os.listdir(path) assuming os.path.isdir(path)"""
+            listing = os.listdir(path)
+            # subtract 1 since a "file" we found was actually this directory
+            t.total += len(listing) - 1
+            # fancy way to give info without forcing a refresh
+            t.set_postfix(dir=path[-10:], refresh=False)
+            t.update(0)  # may trigger a refresh
+            return listing
+
+        def recursively_search(path):
+            if os.path.isdir(path):
+                for f in list_found_dir(path):
+                    recursively_search(os.path.join(path, f))
+            else:
+                append_found_file(path)
+
+        recursively_search(path)
+        t.set_postfix(dir=path)
+        t.close()
+        return files
+
+Using ``update(0)`` is a handy way to let ``tqdm`` decide when to trigger a
+display refresh to avoid console spamming.
+
+Writing messages
+~~~~~~~~~~~~~~~~
+
+This is a work in progress (see
+`#737 <https://github.com/tqdm/tqdm/issues/737>`__).
+
+Since ``tqdm`` uses a simple printing mechanism to display progress bars,
+you should not write any message in the terminal using ``print()`` while
+a progress bar is open.
+
+To write messages in the terminal without any collision with ``tqdm`` bar
+display, a ``.write()`` method is provided:
+
+.. code:: python
+
+    from tqdm.auto import tqdm, trange
+    from time import sleep
+
+    bar = trange(10)
+    for i in bar:
+        # Print using tqdm class method .write()
+        sleep(0.1)
+        if not (i % 3):
+            tqdm.write("Done task %i" % i)
+        # Can also use bar.write()
+
+By default, this will print to standard output ``sys.stdout``. but you can
+specify any file-like object using the ``file`` argument. For example, this
+can be used to redirect the messages writing to a log file or class.
+
+Redirecting writing
+~~~~~~~~~~~~~~~~~~~
+
+If using a library that can print messages to the console, editing the library
+by  replacing ``print()`` with ``tqdm.write()`` may not be desirable.
+In that case, redirecting ``sys.stdout`` to ``tqdm.write()`` is an option.
+
+To redirect ``sys.stdout``, create a file-like class that will write
+any input string to ``tqdm.write()``, and supply the arguments
+``file=sys.stdout, dynamic_ncols=True``.
+
+A reusable canonical example is given below:
+
+.. code:: python
+
+    from time import sleep
+    import contextlib
+    import sys
+    from tqdm import tqdm
+    from tqdm.contrib import DummyTqdmFile
+
+
+    @contextlib.contextmanager
+    def std_out_err_redirect_tqdm():
+        orig_out_err = sys.stdout, sys.stderr
+        try:
+            sys.stdout, sys.stderr = map(DummyTqdmFile, orig_out_err)
+            yield orig_out_err[0]
+        # Relay exceptions
+        except Exception as exc:
+            raise exc
+        # Always restore sys.stdout/err if necessary
+        finally:
+            sys.stdout, sys.stderr = orig_out_err
+
+    def some_fun(i):
+        print("Fee, fi, fo,".split()[i])
+
+    # Redirect stdout to tqdm.write() (don't forget the `as save_stdout`)
+    with std_out_err_redirect_tqdm() as orig_stdout:
+        # tqdm needs the original stdout
+        # and dynamic_ncols=True to autodetect console width
+        for i in tqdm(range(3), file=orig_stdout, dynamic_ncols=True):
+            sleep(.5)
+            some_fun(i)
+
+    # After the `with`, printing is restored
+    print("Done!")
+
+Redirecting ``logging``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Similar to ``sys.stdout``/``sys.stderr`` as detailed above, console ``logging``
+may also be redirected to ``tqdm.write()``.
+
+Warning: if also redirecting ``sys.stdout``/``sys.stderr``, make sure to
+redirect ``logging`` first if needed.
+
+Helper methods are available in ``tqdm.contrib.logging``. For example:
+
+.. code:: python
+
+    import logging
+    from tqdm import trange
+    from tqdm.contrib.logging import logging_redirect_tqdm
+
+    LOG = logging.getLogger(__name__)
+
+    if __name__ == '__main__':
+        logging.basicConfig(level=logging.INFO)
+        with logging_redirect_tqdm():
+            for i in trange(9):
+                if i == 4:
+                    LOG.info("console logging redirected to `tqdm.write()`")
+        # logging restored
+
+Monitoring thread, intervals and miniters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``tqdm`` implements a few tricks to increase efficiency and reduce overhead.
+
+- Avoid unnecessary frequent bar refreshing: ``mininterval`` defines how long
+  to wait between each refresh. ``tqdm`` always gets updated in the background,
+  but it will display only every ``mininterval``.
+- Reduce number of calls to check system clock/time.
+- ``mininterval`` is more intuitive to configure than ``miniters``.
+  A clever adjustment system ``dynamic_miniters`` will automatically adjust
+  ``miniters`` to the amount of iterations that fit into time ``mininterval``.
+  Essentially, ``tqdm`` will check if it's time to print without actually
+  checking time. This behaviour can be still be bypassed by manually setting
+  ``miniters``.
+
+However, consider a case with a combination of fast and slow iterations.
+After a few fast iterations, ``dynamic_miniters`` will set ``miniters`` to a
+large number. When iteration rate subsequently slows, ``miniters`` will
+remain large and thus reduce display update frequency. To address this:
+
+- ``maxinterval`` defines the maximum time between display refreshes.
+  A concurrent monitoring thread checks for overdue updates and forces one
+  where necessary.
+
+The monitoring thread should not have a noticeable overhead, and guarantees
+updates at least every 10 seconds by default.
+This value can be directly changed by setting the ``monitor_interval`` of
+any ``tqdm`` instance (i.e. ``t = tqdm.tqdm(...); t.monitor_interval = 2``).
+The monitor thread may be disabled application-wide by setting
+``tqdm.tqdm.monitor_interval = 0`` before instantiation of any ``tqdm`` bar.

+        len(iterable) is used if possible. If float("inf") or as a last
+        resort, only basic progress statistics are displayed
+        (no ETA, no progress bar).
+        If `gui` is True and this parameter needs subsequent updating,
+        specify an initial arbitrary large positive number,
+        e.g. 9e9.
+    leave  : bool, optional
+        If [default: True], keeps all traces of the progress bar
+        upon termination of iteration.
+        If `None`, will leave only if `position` is `0`.
+    file  : `io.TextIOWrapper` or `io.StringIO`, optional
+        Specifies where to output the progress messages
+        (default: sys.stderr). Uses `file.write(str)` and `file.flush()`
+        methods.  For encoding, see `write_bytes`.
+    ncols  : int, optional
+        The width of the entire output message. If specified,
+        dynamically resizes the progress bar to stay within this bound.
+        If unspecified, attempts to use environment width. The
+        fallback is a meter width of 10 and no limit for the counter and
+        statistics. If 0, will not print any meter (only stats).
+    mininterval  : float, optional
+        Minimum progress display update interval [default: 0.1] seconds.
+    maxinterval  : float, optional
+        Maximum progress display update interval [default: 10] seconds.
+        Automatically adjusts `miniters` to correspond to `mininterval`
+        after long display update lag. Only works if `dynamic_miniters`
+        or monitor thread is enabled.
+    miniters  : int or float, optional
+        Minimum progress display update interval, in iterations.
+        If 0 and `dynamic_miniters`, will automatically adjust to equal
+        `mininterval` (more CPU efficient, good for tight loops).
+        If > 0, will skip display of specified number of iterations.
+        Tweak this and `mininterval` to get very efficient loops.
+        If your progress is erratic with both fast and slow iterations
+        (network, skipping items, etc) you should set miniters=1.
+    ascii  : bool or str, optional
+        If unspecified or False, use unicode (smooth blocks) to fill
+        the meter. The fallback is to use ASCII characters " 123456789#".
+    disable  : bool, optional
+        Whether to disable the entire progress bar wrapper
+        [default: False]. If set to None, disable on non-TTY.
+    unit  : str, optional
+        String that will be used to define the unit of each iteration
+        [default: it].
+    unit_scale  : bool or int or float, optional
+        If 1 or True, the number of iterations will be reduced/scaled
+        automatically and a metric prefix following the
+        International System of Units standard will be added
+        (kilo, mega, etc.) [default: False]. If any other non-zero
+        number, will scale `total` and `n`.
+    dynamic_ncols  : bool, optional
+        If set, constantly alters `ncols` and `nrows` to the
+        environment (allowing for window resizes) [default: False].
+    smoothing  : float, optional
+        Exponential moving average smoothing factor for speed estimates
+        (ignored in GUI mode). Ranges from 0 (average speed) to 1
+        (current/instantaneous speed) [default: 0.3].
+    bar_format  : str, optional
+        Specify a custom bar string formatting. May impact performance.
+        [default: '{l_bar}{bar}{r_bar}'], where
+        l_bar='{desc}: {percentage:3.0f}%|' and
+        r_bar='| {n_fmt}/{total_fmt} [{elapsed}<{remaining}, '
+            '{rate_fmt}{postfix}]'
+        Possible vars: l_bar, bar, r_bar, n, n_fmt, total, total_fmt,
+            percentage, elapsed, elapsed_s, ncols, nrows, desc, unit,
+            rate, rate_fmt, rate_noinv, rate_noinv_fmt,
+            rate_inv, rate_inv_fmt, postfix, unit_divisor,
+            remaining, remaining_s, eta.
+        Note that a trailing ": " is automatically removed after {desc}
+        if the latter is empty.
+    initial  : int or float, optional
+        The initial counter value. Useful when restarting a progress
+        bar [default: 0]. If using float, consider specifying `{n:.3f}`
+        or similar in `bar_format`, or specifying `unit_scale`.
+    position  : int, optional
+        Specify the line offset to print this bar (starting from 0)
+        Automatic if unspecified.
+        Useful to manage multiple bars at once (eg, from threads).
+    postfix  : dict or *, optional
+        Specify additional stats to display at the end of the bar.
+        Calls `set_postfix(**postfix)` if possible (dict).
+    unit_divisor  : float, optional
+        [default: 1000], ignored unless `unit_scale` is True.
+    write_bytes  : bool, optional
+        Whether to write bytes. If (default: False) will write unicode.
+    lock_args  : tuple, optional
+        Passed to `refresh` for intermediate output
+        (initialisation, iterating, and updating).
+    nrows  : int, optional
+        The screen height. If specified, hides nested bars outside this
+        bound. If unspecified, attempts to use environment height.
+        The fallback is 20.
+    colour  : str, optional
+        Bar colour (e.g. 'green', '#00ff00').
+    delay  : float, optional
+        Don't display until [default: 0] seconds have elapsed.
+    gui  : bool, optional
+        WARNING: internal parameter - do not use.
+        Use tqdm.gui.tqdm(...) instead. If set, will attempt to use
+        matplotlib animations for a graphical output [default: False].

+.SH OPTIONS
+.TP
+\-h, \-\-help
+Print this help and exit.
+.TP
+\-v, \-\-version
+Print version and exit.
+.TP
+\-\-desc=\f[I]desc\f[R]
+str, optional.
+Prefix for the progress bar.
+.TP
+\-\-total=\f[I]total\f[R]
+int or float, optional.
+The number of expected iterations.
+If unspecified, len(iterable) is used if possible.
+If float(\(lqinf\(rq) or as a last resort, only basic progress
+statistics are displayed (no ETA, no progress bar).
+If \f[CR]gui\f[R] is True and this parameter needs subsequent updating,
+specify an initial arbitrary large positive number, e.g.\ 9e9.
+.TP
+\-\-leave
+bool, optional.
+If [default: True], keeps all traces of the progress bar upon
+termination of iteration.
+If \f[CR]None\f[R], will leave only if \f[CR]position\f[R] is
+\f[CR]0\f[R].
+.TP
+\-\-ncols=\f[I]ncols\f[R]
+int, optional.
+The width of the entire output message.
+If specified, dynamically resizes the progress bar to stay within this
+bound.
+If unspecified, attempts to use environment width.
+The fallback is a meter width of 10 and no limit for the counter and
+statistics.
+If 0, will not print any meter (only stats).
+.TP
+\-\-mininterval=\f[I]mininterval\f[R]
+float, optional.
+Minimum progress display update interval [default: 0.1] seconds.
+.TP
+\-\-maxinterval=\f[I]maxinterval\f[R]
+float, optional.
+Maximum progress display update interval [default: 10] seconds.
+Automatically adjusts \f[CR]miniters\f[R] to correspond to
+\f[CR]mininterval\f[R] after long display update lag.
+Only works if \f[CR]dynamic_miniters\f[R] or monitor thread is enabled.
+.TP
+\-\-miniters=\f[I]miniters\f[R]
+int or float, optional.
+Minimum progress display update interval, in iterations.
+If 0 and \f[CR]dynamic_miniters\f[R], will automatically adjust to equal
+\f[CR]mininterval\f[R] (more CPU efficient, good for tight loops).
+If > 0, will skip display of specified number of iterations.
+Tweak this and \f[CR]mininterval\f[R] to get very efficient loops.
+If your progress is erratic with both fast and slow iterations (network,
+skipping items, etc) you should set miniters=1.
+.TP
+\-\-ascii=\f[I]ascii\f[R]
+bool or str, optional.
+If unspecified or False, use unicode (smooth blocks) to fill the meter.
+The fallback is to use ASCII characters \(rq 123456789#\(lq.
+.TP
+\-\-disable
+bool, optional.
+Whether to disable the entire progress bar wrapper [default: False].
+If set to None, disable on non\-TTY.
+.TP
+\-\-unit=\f[I]unit\f[R]
+str, optional.
+String that will be used to define the unit of each iteration [default:
+it].
+.TP
+\-\-unit\-scale=\f[I]unit_scale\f[R]
+bool or int or float, optional.
+If 1 or True, the number of iterations will be reduced/scaled
+automatically and a metric prefix following the International System of
+Units standard will be added (kilo, mega, etc.)
+[default: False].
+If any other non\-zero number, will scale \f[CR]total\f[R] and
+\f[CR]n\f[R].
+.TP
+\-\-dynamic\-ncols
+bool, optional.
+If set, constantly alters \f[CR]ncols\f[R] and \f[CR]nrows\f[R] to the
+environment (allowing for window resizes) [default: False].
+.TP
+\-\-smoothing=\f[I]smoothing\f[R]
+float, optional.
+Exponential moving average smoothing factor for speed estimates (ignored
+in GUI mode).
+Ranges from 0 (average speed) to 1 (current/instantaneous speed)
+[default: 0.3].
+.TP
+\-\-bar\-format=\f[I]bar_format\f[R]
+str, optional.
+Specify a custom bar string formatting.
+May impact performance.
+[default: `{l_bar}{bar}{r_bar}'], where l_bar=`{desc}:
+{percentage:3.0f}%|' and r_bar=`| {n_fmt}/{total_fmt}
+[{elapsed}<{remaining}, \(cq \(cq{rate_fmt}{postfix}]' Possible vars:
+l_bar, bar, r_bar, n, n_fmt, total, total_fmt, percentage, elapsed,
+elapsed_s, ncols, nrows, desc, unit, rate, rate_fmt, rate_noinv,
+rate_noinv_fmt, rate_inv, rate_inv_fmt, postfix, unit_divisor,
+remaining, remaining_s, eta.
+Note that a trailing \(lq:\(rq is automatically removed after {desc} if
+the latter is empty.
+.TP
+\-\-initial=\f[I]initial\f[R]
+int or float, optional.
+The initial counter value.
+Useful when restarting a progress bar [default: 0].
+If using float, consider specifying \f[CR]{n:.3f}\f[R] or similar in
+\f[CR]bar_format\f[R], or specifying \f[CR]unit_scale\f[R].
+.TP
+\-\-position=\f[I]position\f[R]
+int, optional.
+Specify the line offset to print this bar (starting from 0) Automatic if
+unspecified.
+Useful to manage multiple bars at once (eg, from threads).
+.TP
+\-\-postfix=\f[I]postfix\f[R]
+dict or *, optional.
+Specify additional stats to display at the end of the bar.
+Calls \f[CR]set_postfix(**postfix)\f[R] if possible (dict).
+.TP
+\-\-unit\-divisor=\f[I]unit_divisor\f[R]
+float, optional.
+[default: 1000], ignored unless \f[CR]unit_scale\f[R] is True.
+.TP
+\-\-write\-bytes
+bool, optional.
+Whether to write bytes.
+If (default: False) will write unicode.
+.TP
+\-\-lock\-args=\f[I]lock_args\f[R]
+tuple, optional.
+Passed to \f[CR]refresh\f[R] for intermediate output (initialisation,
+iterating, and updating).
+.TP
+\-\-nrows=\f[I]nrows\f[R]
+int, optional.
+The screen height.
+If specified, hides nested bars outside this bound.
+If unspecified, attempts to use environment height.
+The fallback is 20.
+.TP
+\-\-colour=\f[I]colour\f[R]
+str, optional.
+Bar colour (e.g.\ `green', `#00ff00').
+.TP
+\-\-delay=\f[I]delay\f[R]
+float, optional.
+Don\(cqt display until [default: 0] seconds have elapsed.
+.TP
+\-\-delim=\f[I]delim\f[R]
+chr, optional.
+Delimiting character [default: `\(rsn'].
+Use `\(rs0' for null.
+N.B.: on Windows systems, Python converts `\(rsn' to `\(rsr\(rsn'.
+.TP
+\-\-buf\-size=\f[I]buf_size\f[R]
+int, optional.
+String buffer size in bytes [default: 256] used when \f[CR]delim\f[R] is
+specified.
+.TP
+\-\-bytes
+bool, optional.
+If true, will count bytes, ignore \f[CR]delim\f[R], and default
+\f[CR]unit_scale\f[R] to True, \f[CR]unit_divisor\f[R] to 1024, and
+\f[CR]unit\f[R] to `B'.
+.TP
+\-\-tee
+bool, optional.
+If true, passes \f[CR]stdin\f[R] to both \f[CR]stderr\f[R] and
+\f[CR]stdout\f[R].
+.TP
+\-\-update
+bool, optional.
+If true, will treat input as newly elapsed iterations, i.e.\ numbers to
+pass to \f[CR]update()\f[R].
+Note that this is slow (\(ti2e5 it/s) since every input must be decoded
+as a number.
+.TP
+\-\-update\-to
+bool, optional.
+If true, will treat input as total elapsed iterations, i.e.\ numbers to
+assign to \f[CR]self.n\f[R].
+Note that this is slow (\(ti2e5 it/s) since every input must be decoded
+as a number.
+.TP
+\-\-null
+bool, optional.
+If true, will discard input (no stdout).
+.TP
+\-\-manpath=\f[I]manpath\f[R]
+str, optional.
+Directory in which to install tqdm man pages.

+
+    Parameters
+    ----------
+    urlpath: string or list
+        Absolute or relative filepath(s). Prefix with a protocol like ``s3://``
+        to read from alternative filesystems. To read from multiple files you
+        can pass a globstring or a list of paths, with the caveat that they
+        must all have the same protocol.
+    mode: 'rb', 'wt', etc.
+    compression: string or None
+        If given, open file using compression codec. Can either be a compression
+        name (a key in ``fsspec.compression.compr``) or "infer" to guess the

+    encoding: str
+        For text mode only

+        Passed to TextIOWrapper in text mode
+    name_function: function or None
+        if opening a set of files for writing, those files do not yet exist,
+        so we need to generate their names by formatting the urlpath for
+        each sequence number

+        if writing mode, number of files we expect to create (passed to
+        name+function)
+    protocol: str or None
+        If given, overrides the protocol found in the URL.
+    newline: bytes or None
+        Used for line terminator in text mode. If None, uses system default;
+        if blank, uses no translation.
+    auto_mkdir: bool (True)
+        If in write mode, this will ensure the target directory exists before
+        writing, by calling ``fs.mkdirs(exist_ok=True)``.
+    expand: bool

+        Extra options that make sense to a particular storage connection, e.g.

+        ----------
+        target_protocol: str (optional)
+            Target filesystem protocol. Provide either this or ``fs``.
+        cache_storage: str or list(str)
+            Location to store files. If "TMP", this is a temporary directory,
+            and will be cleaned up by the OS when this process ends (or later).
+            If a list, each location will be tried in the order given, but
+            only the last will be considered writable.
+        cache_check: int
+            Number of seconds between reload of cache metadata
+        check_files: bool
+            Whether to explicitly see if the UID of the remote file matches
+            the stored one before using. Warning: some file systems such as
+            HTTP cannot reliably give a unique hash of the contents of some
+            path, so be sure to set this option to False.
+        expiry_time: int
+            The time in seconds after which a local copy is considered useless.
+            Set to falsy to prevent expiry. The default is equivalent to one
+            week.
+        target_options: dict or None
+            Passed to the instantiation of the FS, if fs is None.
+        fs: filesystem instance
+            The target filesystem to run against. Provide this or ``protocol``.
+        same_names: bool (optional)
+            By default, target URLs are hashed using a ``HashCacheMapper`` so
+            that files from different backends with the same basename do not
+            conflict. If this argument is ``true``, a ``BasenameCacheMapper``
+            is used instead. Other cache mapper options are available by using
+            the ``cache_mapper`` keyword argument. Only one of this and
+            ``cache_mapper`` should be specified.
+        compression: str (optional)
+            To decompress on download. Can be 'infer' (guess from the URL name),
+            one of the entries in ``fsspec.compression.compr``, or None for no
+            decompression.
+        cache_mapper: AbstractCacheMapper (optional)
+            The object use to map from original filenames to cached filenames.
+            Only one of this and ``same_names`` should be specified.
+        cache_storage_mode: int (optional)
+            Permission mode used when creating the cache storage directory,
+            e.g. ``0o700``. The default of ``None`` leaves the directory at
+            the system default (governed by the umask), which is the existing
+            behaviour. Pass an octal mode such as ``0o700`` to keep the cache
+            directory, and so the cached data files within it, readable by the
+            owner only.
