Please help! I'm supposed to be using python so if someone can do this by using a terminal from python or linux that'd be great. Thanks!

1. Factorial. 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, 5! = 1*2*3*4*5 = 120 Write a program that lets the user enter a nonnegative integer and then uses a loop to calculate the factorial of that number. Display the factorial.
