Hi adam. With the aid of Google it seems a Ti83 is a programmable calculator.
I'm not sure what python tutor you are using but it looks like you need to cover some very basic stuff around data types. You may find the Raw Materials topic in my tutor useful to give you a feel for the different types of data in Python. The Talking to the User topic will cover the use of raw_input. And the Branching topic has an examplre very similar to what you are trying to do.
