For this portion of the lab, you will reuse the program you wrote in Lab5 Part1 A. That means you will open the lab you wrote in the previous assignment and change it. You should NOT start from scratch. Also, all the requirements/prohibitions from the previous lab MUST also be included /omitted from this lab. Redesign the solution in the following manner:

1. All the functions used are value-returning functions. (LO 1)
2. Put the functions in an external module and let the main program import the module. (LO 4)
3. Save the program as firstname_lastname_Lab5Ba. py where you will replace firstname and lastname with your actual first and last name.
