Understanding Python’s if Statement

The if statement lets your program make decisions. Let’s explore different ways to use it with properly formatted examples.

1. Basic if Statement

temperature = 35
if temperature > 30:
    print("It’s a hot day!")
    

2. if-else Statement

age = 16
if age >= 18:
    print("You are eligible to vote")
else:
    print("You are not eligible to vote")
    

3. if-elif-else Statement

marks = 85
if marks < 40:
    print("Fail")
elif marks >= 75:
    print("Distinction")
else:
    print("Pass")
    

4. Nested if Statement

num = 15
if num > 0:
    if num % 2 == 0:
        print("Positive even number")
    else:
        print("Positive odd number")
    

5. Real-World Example: Discount

amount = 1200
discount = 0

if amount > 2000:
    discount = 20
elif amount > 1000:
    discount = 10
else:
    discount = 5

final_amount = amount - (amount * discount / 100)
print("Discount applied:", discount, "%")
print("Final bill:", final_amount)
