In mathematics, the notation n! represents the factorial of the nonnegative integer n. The factorial of n is the product of all the nonnegative integers from 1 to n. For example,

7! = 1 X 2 X 3 X 4 X 5 X 6 X 7 = 5,040

and

4! = 1 X 2 X 3 X 4 = 24

Write a program that lets the user enter a nonnegative integer then uses a loop to calculate the factorial of that number. Display the factorial.  in python
