Factorial Numbers (adapted from \#12) - Save the file as ch2_ex3.py In mathematics, the notation n ! represents the factorial of the nonnegative integer n. The factorial of n is the product of all the non-negative integers from 1 to n. For example: 7!=1234567=5,040 and 4!=1234=24 Write a program that lets the user enter a nonnegative integer then uses a loop to calculate and display the factorial of that number. Your output should be formatted like the following: Enter a non-negative integer: 10 The factorial of 10 is: 1!=1234567891=3,628,800 Another example: Enter a non-negative integer: 5 The factorial of 5 is
