How to divide code into functions

[rkdarst]

Question some people may have: When I make functions, how do you avoid adding more and more input arguments and returned variables to make it general enough for everything you do?

The solution (I think) would be something related to composing functions, or as I would say, separate things into different abstraction layers (input, preprocessing, transformation, analysis, combining), each of which does one thing. More on this with my next suggestion for the lesson.

that's a good question to cover in the material!
