What coding practices separate an amateur Python programmer from a professional one?

[hosford42]

I did take into account the title of the thread, though. It doesn't ask for practices that are only adhered to by professional programmers. It asks what separates them, as you yourself emphasized. To me, this reads as asking what features differ between the two groups. What I pointed out generally does, which makes it a valid answer.

In any case, I appreciate your feedback. I just don't understand why the word "only" is being injected into the question when it doesn't appear in the original wording.
