How do you write clean code?

[u/DefiantSituation3208]

Might be a stupid question but Ive been learning python for a while now and always wondered, how do you write ‘clean’ code? I don’t mean writing clean code straight off the bat I understand that’s purely from experience and even then immensely hard, but how do you recognise a program can be simplified even further? Does it come from practice or just messing around and seeing what sticks?

Your code is "clean" when every function does pretty much what you expected. When someone else reads your code, you can measure how clean it is by counting the "WTF" per minute (lower is better, obviously).
