🐍 Python If Else Statements for Beginners

🤔 What are Conditional Statements?

Conditional statements are used to make decisions in Python. They execute different code based on conditions.

✅ if Statement

The if statement runs code only when a condition is true.

age = 18

if age >= 18:
    print("You can vote")

🔄 if else Statement

The else block runs when the if condition is false.

age = 16

if age >= 18:
    print("Adult")
else:
    print("Minor")

🔀 if elif else Statement

elif is used when we have multiple conditions.

marks = 85

if marks >= 90:
    print("Grade A+")

elif marks >= 75:
    print("Grade A")

else:
    print("Need Improvement")

age = 20

if age >= 18:

    if age <= 60:
        print("Eligible")

🚀 Practice Examples

• Check whether a number is positive or negative.
