This document describes several numbers that are important to the overall program. For full credit, you should make at least one of such numbers into a constant so that the constant could be changed and your program would adapt. Some of your code will use conditional execution with if and if/else statements. Part of your grade will come from using these statements properly. Review the portion of lecture 8 about nested if/else statements and factoring them.

It's a coding assignment. Using specific things as shown. For this assignment, you are limited to Python features. A major part of this assignment is demonstrating that you understand parameters and return values. Use functions, parameters, and returns for structure and to eliminate redundancy. For full credit, use at least 4 non-trivial functions other than main. Like on previous assignments, you should not have print statements in your main function. Also, main should be a concise summary of the overall program; main should make calls to several of your other functions that implement the majority of the program's behavior. Your functions will need to make appropriate use of parameters and return values. Each function should perform a coherent task and should not do too large a share of the overall work. Avoid lengthy “chaining” of function calls, where each function calls the next, no values are returned, and control does not come back to main.
