iPython help!

3.13 (Factorials) Factorial calculations are common in probability. The factorial of a nonnegative integer n is written n! (pronounced "n factorial) and is defined as follows: n! = n (n - 1). (n - 2).....1 for values of n greater than or equal to 1, with 0! defined to be 1. So, 5! = 5.4.3.2.1 which is 120. Factorials increase in size very rapidly. Write a script that inputs a nonnega- tive integer and computes and displays its factorial. Try your script on the integers 10, 20, 114 Control Statements and Program Development 30 and even larger values. Did you find any integer input for which Python could not produce an integer factorial value
