A Summary List

In this chapter, you learned the following:

• Lists are used to keep track of zero or more objects. The objects in a list are referred to as items or elements. Each item in the list has a position, referred to as an index, which ranges from zero to one less than the length of the list.

• Lists can contain any type of data, including other lists.

• Lists are mutable, which means that their contents can be modified.

• Slicing is used to create new lists that have the same values or a subset of the values of the originals.

• When two variables refer to the same object, they are called aliases.

• The str.split method divides a string into parts using whitespace or a specified separator, and returns the parts as a list.
