Comparison operators in Python

Introduction

Comparison operators help us check if things are equal, bigger, or smaller. They tell us true or false.

Checking if a password matches the saved one.

Finding out if a number is bigger than another.

Seeing if two words are the same.

Deciding if someone is old enough to enter a game.

Comparing scores to find the winner.

Syntax

Python

value1 operator value2

Operators return True or False.

Common operators: ==, !=, >, <, >=, <=

Examples

Checks if 5 is equal to 5. Result is True.

Python

5 == 5

Checks if 3 is less than 7. Result is True.

Python

3 < 7

Checks if "apple" is not equal to "orange". Result is True.

Python

"apple" != "orange"

Checks if 10 is greater than or equal to 10. Result is True.

Python

10 >= 10

Sample Program

This program compares two numbers using different comparison operators and prints True or False.

Python

a = 10
b = 20
print(a == b)   # False because 10 is not 20
print(a != b)   # True because 10 is not 20
print(a < b)  # True because 10 is less than 20
print(a >= 10) # True because a is equal to 10

Important Notes

Use double equals (==) to check equality, not a single equals (=) which assigns values.

Comparison operators always return a boolean: True or False.

You can compare numbers, text, and other types that support comparison.

Summary

Comparison operators check how two values relate.

They return True or False.

Common operators: ==, !=, >, <, >=, <=
