🚀 Python is fun for all ages! Today, let’s learn about the if condition in Python with easy-to-understand examples and outputs!

The if statement helps the computer make decisions just like we do in real life. Let’s explore with examples!

1. Basic If Condition

Example: Check if a number is positive.

num = int(input("Enter a number: "))  

if num > 0:  
    print("This is a positive number!")  

Input:

5

Output:

This is a positive number!

🔹 Explanation: If the number is greater than 0, the message is printed. Otherwise, nothing happens.

2. If-Else Condition

Example: Check if a number is positive or negative.

num = int(input("Enter a number: "))  

if num > 0:  
    print("This is a positive number!")  
else:  
    print("This is a negative number!")  

Input:

 '-3

Output:

This is a negative number!

🔹 Explanation: If the number is greater than 0, it prints “positive”; otherwise, it prints “negative”.

3. If-Else Condition

Example: Check if a number is positive, negative, or zero.

num = int(input("Enter a number: "))  

if num > 0:  
    print("This is a positive number!")  
elif num == 0:  
    print("This is zero!")  
else:  
    print("This is a negative number!")  

Input:

 0

Output:

This is zero!

🔹 Explanation: If the number is greater than 0, it prints “positive”. If it is 0, it prints “zero”. Otherwise, it prints “negative”.

4. Nested If Condition

Example: Check if a person is eligible to vote

age = int(input("Enter your age: "))  

if age >= 18:  
    if age >= 60:  
        print("You are a senior citizen and can vote!")  
    else:  
        print("You can vote!")  
else:  
    print("You are too young to vote!")  

Input:

65

Output:

You are a senior citizen and can vote!

🔹 Explanation: If the number is greater than 0, it prints “positive”. If it is 0, it prints “zero”. Otherwise, it prints “negative”.

5. Even or Odd Number Check

num = int(input("Enter a number: "))  

if num % 2 == 0:  
    print("This is an even number!")  
else:  
    print("This is an odd number!")  

Input:

7

Output:

This is an odd number!

🔹 Explanation: If the number is divisible by 2, it’s even. Otherwise, it’s odd.

6.Check If a Year is a Leap Year

year = int(input("Enter a year: "))  

if (year % 4 == 0 and year % 100 != 0) or (year % 400 == 0):  
    print("This is a leap year!")  
else:  
    print("This is not a leap year!")  

Input:

2024

Output:

This is a leap year!

🔹 Explanation: A year is a leap year if it is divisible by 4 but not by 100 unless also divisible by 400.

7. Check If a Person Can Enter a Theme Park Ride

height = int(input("Enter your height in cm: "))  

if height >= 120:  
    print("You can go on the ride!")  
else:  
    print("Sorry, you are not tall enough for the ride. ")  

Input:

110

Output:

Sorry, you are not tall enough for the ride. 

🔹 Explanation: If the height is 120 cm or more, the person can go on the ride. Otherwise, they cannot.

8. Check If a Student Passes the Exam

Example: Check if a person is eligible to vote

score = int(input("Enter your score: "))  

if score >= 50:  
    print("Congratulations! You passed the exam! ")  
else:  
    print("Sorry, you failed. Try again next time! ")  

Input:

45

Output:

Sorry, you failed. Try again next time!

🔹 Explanation: If the score is 50 or more, the student passes; otherwise, they fail.

4. Check If a Number is Between Two Values

num = int(input("Enter a number: "))  

if 10 <= num <= 20:  
    print("Your number is between 10 and 20!")  
else:  
    print("Your number is outside the range!")  

Input:

15

Output:

Your number is between 10 and 20!

🔹 Explanation:The condition 10 <= num <= 20 checks if the number falls within this range.

10. Simple Yes/No Decision Game

choice = input("Do you like Python? (yes/no): ").lower()  

if choice == "yes":  
    print("That's awesome! Python is great! ")  
else:  
    print("No worries! Maybe you'll like it someday! ")  

Input:

yes

Output:

That's awesome! Python is great!

🔹 Explanation: The program asks for input and checks if the answer is “yes” or “no”.

Final Thoughts: Why If Condition is Important?

✅ The if condition allows us to make decisions in Python, just like in real life!
✅ You can use if, if-else, if-elif-else, and nested if conditions to create smart programs!
✅ These examples help beginners, students, and even adults learn Python easily!
