The beginning as in early enough in a Python tutorial where you’ll learn something, or at least clarify your understanding - you seem to be confused that numbers and functions aren’t the same, for example. I suspect then that there are other things missing and that’s preventing you from making progress with this project - that’s also backed up by looking through your other threads and seeing your confusion there. You need to get to grips with the language and understand what it can do before trying to apply it to sophisticated projects. As was mentioned in some of your other threads (e.g. Typing (newb) arrows and colons and I need an expert - #2 by mdickinson) there might be more appropriate tools for what you’re trying to do.
