Python Logical and Bitwise NOT Operators

In Python, not is used for Logical NOT operator, and ~ is used for Bitwise NOT. Here, we will see their usages and implementation in Python.

1. Python Logical NOT (not) Operator

Logical NOT (not) operator is used to reverse the result, it returns False if the result is True; True, otherwise.

Python Program of Logical NOT (not) Operator

# Logical NOT (not) operator

x = True
y = False

# printing the values
print("x: ", x)
print("y: ", y)

# 'not' operations
print("not x: ", not x)
print("not y: ", not y)

Output

x:  True
y:  False
not x:  False
not y:  True

2. Python Bitwise NOT (~) Operator

Bitwise NOT (~) operator is used to invert all the bits i.e. it returns the one's complement of the number.

Python Program of Bitwise NOT (~) Operator

# Bitwise NOT (~) operator

x = True
y = False

# printing the values
print("x: ", x)
print("y: ", y)

# '~' operations
print("~ x: ", ~ x)
print("~ y: ", ~ y)

# assigning numbers
x = 123
y = 128

# printing the values
print("x: ", x)
print("y: ", y)

# '~' operations
print("~ x: ", ~ x)
print("~ y: ", ~ y)

Output

x:  True
y:  False
~ x:  -2
~ y:  -1
x:  123
y:  128
~ x:  -124
~ y:  -129
