Answer 1

You can find factorial by many ways. Either you use "math" module or write a complete function. For example: Calcuating the factorial of number 5

import math
print(math.factorial(5))

OR 

def factorial(n):

    if n == 0:

        return 1

    else:

        return n * factorial(n-1)

factorial(5)    

Output - 120
