One of the most important features of Python is managing data structures. Let’s take a look at them.

Numbers

The numbers in Python can be any of the following:

• Integers, or int

• Floating points, or float

• Complex

• Booleans—that is, True or False

Let’s look at some examples:

# create an object containing an integer (int)

>>> n1 = 19

>>> type(n1)

<type 'int'>

# a float

>>> n2 = 7.5

>>> type(n2)

<type 'float'>

# a Boolean (True/False)

>>> n3 = True

>>> type(n3)

<type 'bool'>

# a complex number

>>> n4 = 3j

>>> type(n4)

<type 'complex'>

Container Objects
