Queues Python Introduction
As previously mentioned, a queue is a data structure that contains an ordered set of data that follows a
FIFO (first in, first out) protocol. You can visualize it as a line at a deli:
The customer at the front of the line (equivalent to the head in a queue) is the first customer to... |

Queues Python Size
Bounded queues require limits on the number of nodes that can be contained, while other queues don’t. To account for
this, we will need to make some modifications to our Queue class so we can keep track of and limit size where needed.
We’ll be adding two new properties to help us out here:

#Write a python function stats() that takes name of text file as an argument. The function
#should print the number of lines, words, and characters in the file. For example,

#Word count: 20
#Character count: 98
def stat(txt):
num_lines = 0
num_words = 0
num_chars = 0
