General coding rules

Question

Hey everybody. I'm looking for documentations more general about coding (python in particular). How to write proper code. Good uses of docstring. And all sorts of basic rules about writing that could help. I'm a beginner and sometimes I mix a bit everything between my class, func,.. and often have the "unrefered" error if I don't use the global statement (which I've read is pretty bad to use).
Hope all that make sens
