Martin's 'Clean Code'. Learn to use meaningful naming, modular functions, proper error handling, and consistent formatting to enhance your code quality. Avoid common pitfalls like excessive comments, code duplication, and side effects. Test-Driven Development (TDD) and Command Query Separation are also discussed as vital practices for robust code. ## Full article daily.dev links to this article rather than hosting it.

I tend to use this for a situation like "if output == 1: return" for example. I keep it a simple one liner because the logic is straight forward and reduces a few lines for such basic logic. Is this fine for my example or not? Thanks! **@svensvoboda** · 0 upvotes > Awsome article, with examples. Love this GG. **@sodero** · 0 upvotes > Puede parecer algo básico y elemental, pero creo que el publico se renueva, me parece muy bueno que se citen y recomienden lecturas de libros que son referencias en la industria. Por otro lado nunca esta de mas repasar estos principios y lecciones. ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#tdd](https://daily.dev/tags/tdd) [View this post on daily.dev](https://daily.dev/posts/python-clean-code-stop-writing-bad-code-lessons-from-uncle-bob-6zaxzazi4) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Python Clean Code: Stop Writing Bad Code — Lessons from Uncle Bob","url":"https://daily.dev/posts/python-clean-code-stop-writing-bad-code-lessons-from-uncle-bob-6zaxzazi4","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/python-clean-code-stop-writing-bad-code-lessons-from-uncle-bob-6zaxzazi4"},"datePublished":"2024-09-09T07:35:14.235Z","dateModified":"2024-12-09T12:58:05.282Z","description":"Transform messy, unorganized code into clean, readable, and maintainable Python code by applying key principles from Robert C.
