This code should prompt the user for a value, and then compute (and print out) the factorial of that value. Recall that n! = 1 * 2 * 3 * ... * (n-1) * n. 0! is defined to be 1

$ python3 factorial.py Enter a number: 1 1! = 1 $ python3 factorial.py Enter a number: 2 2! = 2 $ python3 factorial.py Enter a number: 3 3! = 6 $ python3 factorial.py Enter a number: 4 4! = 24 $ python3 factorial.py Enter a number: 5 5! = 120 $ python3 factorial.py Enter a number: 10 10! = 3628800 $ python3 factorial.py Enter a number: 0 0! = 1
