Lists

Python, unlike other programming languages, such as
C++ and Java, doesn’t have arrays. If you want to store a
bunch of values, you can use a list. You can use a variable
to store a collection of items in a list. To create a list, you
assign the contents of the list to a variable with the = and
[] and separate the items with commas, as in this
example:

>>> kids = ['Caleb', 'Sydney', 'Savannah']

>>> kids

['Caleb', 'Sydney', 'Savannah']

A list can contain any Python object, such as integers,
strings, and even other lists. A list can also be empty and
is often initialized in an empty state for programs that
pull data from other sources. To initialize a list in an
empty state, you just assign two brackets with nothing in
them or you can use the built-in list() function:

emptylist = []

emptylist2 = list()
