Description
Calculating the Factorial of a Number
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 up through 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
Design a program, in Python, that asks the user to enter a nonnegative integer and then displays the factorial of that number.
