Question 09:
Write a Python program to check if a number is positive, negative, or zero.

Answer:
def main(num: int) -> None:
    if num > 0:
        print(f"{num} is positive.")
    elif num < 0:
        print(f"{num} is negative.")
    else:
        print("The number is zero.")
    

if __name__ == '__main__':
    main(10)
    main(-5)
    main(0)


Output:
10 is positive.
-5 is negative.
The number is zero.
