10 Python Anti-Patterns That Are Breaking Your Code | Issue #53

Published 6 days ago • 1 min read

Hi there,

​

You ever look at some Python code and think, “Wait… why did we do it like this?”

​

​This week’s video is all about the Python anti-patterns that sneak into our codebases—sometimes looking clever, sometimes just copied from bad tutorials. But they can seriously hurt long-term maintainability. 🚨

​

I walk through 10 real-world examples, from using exceptions as control flow to awkward class structures, and even show how hardcoding UI strings can make your app a localization nightmare.

​

Have a great weekend, and let’s keep our Python clean and our codebases happy!

​

Cheers,

Arjan

Hi there, I’m emailing you from prison. 🚨 No, not like that. The new ArjanCodes office is inside a 19th-century prison in Utrecht. And it’s actually… amazing. The cells are now offices, the vibe is creative, and it’s got just the right kind of gloominess for video production (because direct sunlight and camera lenses don’t mix). In this week’s video, I take you on a little tour of the space and talk about what’s ahead for the channel. After a year of scaling down, I’m finding more balance—and...

Hi there, We all know type hints can catch bugs before runtime. 🐛 But what if I told you they’re also one of your best tools for designing better software? In this week’s video, I show how type hints can lead to smarter choices about inputs, outputs, and even class structure — all without adding complexity. It’s the kind of thinking that leads to better architecture and fewer “why did I do this?” moments later on. 😌 And yes, I also drop a few tips you’ve probably never heard about inputs and...

Hi there, If you’ve ever used Python decorators, you know they look like a clean way to add functionality. But have you ever struggled to debug a decorated function? Or wondered why your type hints suddenly break? Or spent way too much time figuring out why your decorators aren’t working as expected? 🫠 🚨 Decorators introduce hidden complexity that can turn your code into a nightmare. And honestly? I think they’re overused. In this week’s video, I explain: Why decorators break type safety and...
