CODE USING PYTHON ( python 3 preferred) PLEASE:

Be sure to write clear comments throughout when coding this and make sure the code passes the unit test. Both images task of the assignment and the unit test are attached below. I'm not sure but It may involve using dictionaries, lists, list comprehensions. Make sure it isn't too advanced either; something that a person that's taking an intro to python course could do. Just use your better judgment please and thank you.
