Boolean values (True and False) in Python

Introduction

Boolean values help us decide between two choices: yes or no, true or false.

Checking if a light is on or off.

Deciding if a user is logged in or not.

Testing if a number is bigger than another.

Verifying if a door is locked or unlocked.

Syntax

Python

True
False

Boolean values always start with a capital letter in Python.

They represent the idea of yes/no or on/off in programs.

Examples

Here, we say it is raining (True) and not sunny (False).

Python

is_raining = True
is_sunny = False

If the light is on (True), we print a message.

Python

light_on = True
if light_on:
    print("The room is bright")

Sample Program

This program checks if you are hungry. If yes (True), it suggests eating.

Python

is_hungry = True
if is_hungry:
    print("Time to eat!")
else:
    print("Not hungry now.")

Important Notes

Boolean values are often used in conditions to control what the program does.

Remember, True and False are special words in Python, not strings.

Summary

Boolean values are True or False.

They help programs make decisions.

Use them to check conditions simply.
