Apply the PEP 8 style guide by renaming unclear variables and functions to reveal intent and extracting long blocks into small named functions. Keep the public interface and observable output identical so readability improves without changing behavior.

Write comments that explain why a design decision was made, introduce a language idiom at its first occurrence, or warn about edge cases and invariants. Avoid comments that merely restate the syntax or narrate obvious control flow.

A tutorial README should include a project overview, setup instructions, a how-it-works explanation, a usage example, and optionally a sample output section. Start with an H1 naming the project and test the setup command and example before publishing.

No, a didactic refactor must preserve behavior, file encoding, and line endings exactly. The script should still compile and produce identical output after renaming, restructuring, and commenting.

Yes, the same three-step procedure of refactoring, commenting, and writing a tutorial applies to any language. Python with PEP 8 is the example, but the workflow adapts to stacks like Java 21 and TypeScript.
