Factorialof a non-negative integer x, denoted by x!is the product of all positive integers less than or equal to x. For example, 5! = 1x2x3x4x5 = 120. In Python, the function factorial(x)in math module can be used to find the factorial of non-negative integer x.For example:from math import factorialx = 5f = factorial(x)Then variable fwill assign the factorial of 5, that is 120.Complete the following function called xFactorial that computes and return the factorial of x for any number x>0. Return 1 for x<=0.def xFactorial(x):
