List.py

'''
Lists are used to store multiple items in a single variable.

Lists are one of 4 built-in data types in Python used to store collections of data, 
the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage.

Lists are created using square brackets.

List items are ordered, changeable, and allow duplicate values.
