Please write in python. Also, I am using MU editor. Thanks

Write a program that can accept one input, a positive integer. The program should calculate the factorial value for that number. In mathematical terms, the factorial of a number N is the product of positive integers between 1 and N. So for instance: . 4 factorial = (1*2*3* 4) = 24 . 5 factorial = (1*2*3*4* 5) = 120 6 factorial = (1 * 23*4*5*6) = 720 . 7 factorial = (1 23*4*5*6* 7) = 5040 Use a while-loop to calculate and print the factorial for the input number. For instance: Enter factorial to calculate: 5 5 factorial = 120 Name the program prep9.py). Make sure that gradescope gives you the points for passing the test case(s)
