This lesson introduces lists, a Python data structure that allows us to store multiple values or items under a single variable name.

Summary:
A list stores many values in a single structure
Lists may contain values of different types
The empty list contains no values
Use an item's index to fetch it from a list
Lists' values can be replaced by assigning to them
Appending items to a list lengthens it
if `.append()` is used to add a collection of items (such as a list), they are added as a single new list item
The list method `.extend()` can be used with a collection of items (such as another list) to create a flat list
The list methods `.remove()` and `.pop()` can be used to delete list items, using either their value or index, respectively
Character strings can be indexed like lists
Character strings are immutable, whereas lists are mutable (changable)
Indexing beyond the end of the collection is an error, but slicing can include indexes that do not occur in the list
