Python Conditional Statements (if, elif, else) with Examples

 ✍️Introduction

In programming, we often need to make decisions.

For example:

• If marks ≥ 40 → Pass

• Else → Fail

Python uses conditional statements to make such decisions.

In this article, you will learn:

• What conditional statements are

• if, elif, else statements

• Simple and clear examples

What are Conditional Statements in Python?

Conditional statements allow a program to execute different code blocks based on conditions.

Python checks the condition:

• If True → code runs

• If False → code is skipped

1️⃣ if Statement

The if statement executes code only if the condition is true.

Syntax:

if condition:

    statement

Example:

age = 18

if age >= 18:

    print("You are eligible to vote")

2️⃣ if–else Statement

The else block runs when the if condition is false.

Syntax:

if condition:

    statement

else:

    statement

Example:

marks = 35

if marks >= 40:

    print("Pass")

else:

    print("Fail")

3️⃣ if–elif–else Statement

Used when there are multiple conditions.

Syntax:

if condition1:

    statement

elif condition2:

    statement

else:

    statement

Example:

marks = 75

if marks >= 90:

    print("Grade A")

elif marks >= 60:

    print("Grade B")

else:

    print("Grade C")

4️⃣ Nested if Statement

An if inside another if is called a nested if.

Example:

age = 20

citizen = True

if age >= 18:

    if citizen:

        print("Eligible to vote")

Comparison Operators Used in Conditions

      Operator                         Meaning

           ==                                   Equal to

           !=                                   Not equal

           >                                   Greater than

          <                                      Less than

         >=                            Greater than or equal

        <=                               Less than or equal

Logical Operators in Conditions

       Operator                     Meaning

         and                     Both conditions true

         or                      Any one condition true

        not                           Reverse result

Example:

age = 25

if age > 18 and age < 60:

    print("Working age group")

❌ Common Mistakes by Beginners

❌ Forgetting colon :

❌ Wrong indentation

❌ Using = instead of ==

Correct example:

if a == 10:

    print("Correct")

🎯 Why Conditional Statements are Important?

• Used in decision making

• Core concept of programming

• Important for exams & interviews

• Used in real-life applications

Real-Life Example

balance = 500

if balance >= 1000:

    print("Withdraw allowed")

else:

    print("Insufficient balance")

Conclusion

Python conditional statements help programs think and decide.

Understanding if, elif, and else is very important for writing logical programs.
