Booleans in Python

Boolean is an in-built data type of Python. It is used to represent two values: True or False.

For example, 1 <= 2 is true but 1 == 0 is false.

You can check the data type of True and False using the built in type()function.

More about functions in these posts- Functions in Python and Function Arguments in Python

For example-

print(type(True))

print(type(False))

The output-

<class 'bool'>
<class 'bool'>

You cannot assign values to True or False because they are keywords in Python and act like constants. If you assign a value to True or False, it will raise a SyntaxError.

Arithmetic Operations on Boolean Values

In Python, True has the value of 1 and False has the value of 0. Hence, they can be used to perform arithmetic operations.

For example-

print(True+False)

print(True*3)

print(False/2)

The output-

1
3
0

Here’s another way to find if an expression is true or false-

a=7
b=23
print(bool(a=b))

The output-

False

This code gives the output False as 7 is not equal to 23.

Numbers as Booleans

Numbers can be used as Boolean values by using Python’s in-built bool() feature. Any integer, floating-point number or complex number having 0 as its value is considered False, while if they are having value as any positive or negative number then it is considered as True.

For example-

a=0
b=1
c=-9.4

print(bool(a))
print(bool(b))
print(bool(c))

The output-

False
True
True

Booleans created by comparison operators

Booleans can be created by using comparison operators also.

For example-

a=5
b=10

print(a==b)
print(a!=b)
print(a<b)
print(a>b)
print(a<=b)
print(a>=b)

The output-

False
True
True
False
True
False
