Logical Operators

In Python, Logical operators are used on conditional statements (either True or False). They perform Logical AND, Logical OR and Logical NOT operations.

Operator	Meaning	Example
and	Logical AND - True if both operands are true	5 > 3 and 3 > 2 = True
or	Logical OR - True if either operand is true	5 > 3 or 3 > 2 = True
not	Logical NOT - True if operand is false	not 5 > 3 = False

Example 1: Logical operators in Python

x = True
y = False

print(f'x and y is {x and y}')

print(f'x or y is {x or y}')

print(f'not x is {not x}')

Output:

x and y is False
x or y is True
not x is False

and will result into True only if both the operands are True

The truth table for and is given below:

A	B	A and B
True	True	True
True	False	False
False	True	False
False	False	False

or will result into True if any of the operands is True.

The truth table for or is given below:

A	B	A or B
True	True	True
True	False	True
False	True	True
False	False	False

not operator is used to invert the truth value.

The truth table for not is given below:

A	not A
True	False
False	True

some example of their usage are given below

>>> True and False
False
>>> True or False
True
>>> not False
True
