Lists are a datatype you can use to store a collection of different pieces of information as a sequence under a single variable name. (Datatypes you've already learned about include strings, numbers, and booleans.)
You can assign items to a list with an expression of the form
list_name = [item_1, item_2]
with the items in between brackets. A list can also be empty:
empty_list = .
Lists are very similar to strings, but there are a few key differences.
