Question

Problem 1 (Factorial with loops) Complete the function factorial_loop(num) that takes an integer num and returns the value of num!, i.e., num! = num * (num-1) * (num-2) * ... * 1. This function must use a loop (iteration) to compute the value of num!.

(in python)

Answer 1

def factorial_loop(num):
    result = 1
    for i in range(1, num + 1):
        result *= i
    return result


# Testing the function here. ignore/remove the code below if not required
n = int(input("Enter a positive integer: "))
print("Factorial of", n, "is", factorial_loop(n))
