1. Even/Odd Checker

Write a Python program to check if a given number is even or odd using boolean variables.

Sample Solution:

Code:

def is_even(number):
    # Return True or False.
    return number % 2 == 0

def main():
    try:
        number = int(input("Input a number: "))
        if is_even(number):
            print(f"{number} is an even number.")
        else:
            print(f"{number} is an odd number.")
    except ValueError:
        print("Invalid input. Please enter a valid number.")

if __name__ == "__main__":
    main()

Output:

Input a number: 10
10 is an even number.

Input a number: 7
7 is an odd number.

When we run the program, it prompts the user to input a number. It then uses the “is_even()” function to determine if the number is even or odd and prints the appropriate message.
