Python - Comparison Operators

Python provides operators that can be used to compare values or values within variables. As as the name implies.

The comparison are like equal to and not equal to. Also known as equality operators.

Both comparison operators, equal to(==) and not equal to(!=) gives resultant value in boolean i.e either True or False after evaluation.

Equal to(==) operator(double equal) checks, whether operands surrounding equal to operator are same or not. Whereas the single equal(=) is used for assigning RHS(Right Hand Side) value or expression to LHS(Left Hand Side).

The not equal to(!=) operator in Python checks, whether operands surrounding operator are different or equal.

In this article, you will find Comparison operators provided by Python.

Comparison operators

Basic comparisons performed on operands/variables with the use of equality operators.

OperatorDescriptionExample
==Equala == b
!=Not Equala != b
  • Both of these operators == and != are binary operators.
  • These operators also follow the same general structure of Operand Operator Operand, meaning that an operator is always surrounded by two operands.
  • For example, an expression a == b is a binary operation, where a and b are the two operands and == is an operator.
  • If value of a & b are same then you will get True as value else False.

Example for different value in operands

a = 12
b = 24

print(a == b)
#Output: False

print(a != b)
#Output: True

Example for same value in operands

a = 12
b = 12

print(a == b)
#Output: True

print(a != b)
#Output: False

Generally these operators are use with if statements.

Program to check whether the entered number is zero or non-zero

# ZeroNonZero.py
num = int(input('Enter integer: '))

if num == 0 :
    print('Zero')
else :
    print('Non-zero')
