# How to port Python 2 Code to Python 3 {#pyporting-howto}

author
:   Brett Cannon

Python 2 reached its official end-of-life at the start of 2020. This means that no new bug reports, fixes, or changes will be made to Python 2 - it\'s no longer supported: see `373`{.interpreted-text role="pep"} and [status of Python versions](https://devguide.python.org/versions).

If you are looking to port an extension module instead of pure Python code, please see `cporting-howto`{.interpreted-text role="ref"}.

The archived [python-porting](https://mail.python.org/pipermail/python-porting/) mailing list may contain some useful guidance.

Since Python 3.11 the original porting guide was discontinued. You can find the old guide in the [archive](https://docs.python.org/3.10/howto/pyporting.html).
