Your submission should consist of a single .py file, should meet all of the following requirements:

Full pseudocode, along with the Input List and Output List, should be included in the comments.

It must have at least one output.

If it has user input (which is up to you), then it must validate the user input. This means the user is not allowed to just enter any value. You must check the value, and ask the user to enter it again, and repeat this loop until the user enters a valid value.

Your program must use at least one class and must create and use objects in a meaningful way. Values that should be part of your class should be represented as properties, and functions that should be part of your class should be represented as methods. You are encouraged to use multiple classes with inheritance and polymorphism, but that isn't required for full credit.

Your program should be organized into separate modules. Each module should be "cohesive" and should only do one thing.

Use parameters and arguments to pass values into your modules (don't use global variables). Most values will probably end up being properties of your objects, and objects or arrays of objects will be passed into your modules. Use methods appropriately.

The Python code should run correctly, and the logic should match your pseudocode.
