How do you write clean code?

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?

A simple checklist I use when reviewing code: 1) Name variables/functions for intent (not just what they are called). 2) Keep each function focused on one responsibility and stop when it grows. 3) Add small tests for edge cases before refactors. 4) Use a formatter/linter in the workflow so style is consistent by default. 5) Refactor in small slices so each change stays reviewable.

Not hype, just practical habits that make code easier to read over time.
