What is a Boolean Data Type?

It's time to move to the Boolean data type. Variables that are Boolean data types can take the following values: either False or True.

Keywords False and True are capitalized, if we write lowercase we will get an error.

Input:
a = True
print(type(a))

b = False
print(type(b))

Output:
<class 'bool'>
<class 'bool'>

In Python, data types such as Boolean and integer are very interrelated, namely the default Boolean value False is represented by an integer 0, and Boolean value True is represented by an integer 1.
