1 ) Write a program that checks whether the given input is an even number or an  odd number ?

Solution :

num = int(input(“Enter the number: “)) # Taking input from the user and converting it to an integer

if num % 2 == 0: # Checking if the number is divisible by 2 (i.e., even)

print(f”The given number is even: {num}”) # Printing that the number is even

else: # If the condition above is false, the number is odd

print(f”The given number is odd: {num}”) # Printing that the number is odd

Line-by-Line Explanation:

1. num = int(input("Enter the number: "))
   • The program takes input from the user using input().
   • input() always takes input as a string, so we use int() to convert it to an integer.
2. if num % 2 == 0:
   • % is the modulus operator, which returns the remainder when num is divided by 2.
   • If num % 2 == 0, it means the number is even because it is perfectly divisible by 2.
3. print(f"The given number is even: {num}")
   • If the condition num % 2 == 0 is true, this statement is executed.
   • The f"" (formatted string) allows us to directly insert the value of num inside the string.
4. else:
   • If the if condition is false (i.e., num % 2 is not 0), then the number is odd.
5. print(f"The given number is odd: {num}")
   • If the number is not even, this statement is executed, indicating that the number is odd.
