Spaghetti Code

[kucingkembar]

sorry for my bad English, or if I write in the wrong Section

I can do some Python coding,
but the ending of my code usually ends as Spaghetti Code,
I see a lot of professionals Coder (usually in GitHub) is easy to read, easy to debug, and easy to mod,
is there any site, book, or youtube video to teach me about that?

and the second question is:
is there any simulation site to test "programmer" skill levels?

thank you for reading,
have a nice day
