I am a beginner in Pygame (and programming in general) and tried to make a Flappy Bird game. It works fine, but I'm sure the code has a lot of scope for improvement. It is completely procedural, and while I do want to make it object oriented to clean it up, I'm not sure how to go about it. For eg: Bird will be an object, but what about the wall pairs? Will all wall pairs be one object? Will one wall pair be one object? It is all getting a bit confusing.

(Also I'm aware they are not device independent paths)
