Program in python to print factorial of a number using for loop

Objective: Write a program in python to print factorial of a number using for loop.

Code:

# Prompt user for input

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

# Check if the number is negative, zero, or one

if num < 0:

    print("Factorial is not defined for negative numbers.")

elif num == 0 or num == 1:

    print("The factorial of", num, "is 1.")

else:

    factorial = 1

    # Loop through numbers from 2 to num (inclusive)

    for i in range(2, num + 1):

        factorial *= i

    print("The factorial of", num, "is", factorial)
