I dont get the question completely but i gues this would help
def iter_factorial(n): factorial=1 n = input("Enter a number: ") factorial = 1 if int(n) >= 1: for i in range (1,int(n)+1): factorial = factorial * i return factorial num=int(input("Enter the number: ")) print("factorial of ",num," (iterative): ",end="") print(iter_factorial(num))If this does not help, try to go through this article factorial in python
