Answer 1

# Python 3.9.5

def recur_factorial(n):
   if n == 1:
       return n
   else:
       return n*recur_factorial(n-1)


def iterat_factorial(n):
    num_fac = 1
    for i in range(1, n+1):
        num_fac *= i
    return num_fac


def main():
    n = int(input('Enter number: '))
    print('Recursive factorial: ', recur_factorial(n))
    print('Iterable factorial: ', iterat_factorial(n))


if __name__ == '__main__':
    main()
