Stop Passing So Many Arguments in Python

Stop Passing So Many Arguments in Python | Issue #77

Published 1 day ago • 1 min read

Hi there,

Have you ever found yourself writing functions like this?

def render_article(article_id, db, logger, user, config, feature_flags, etc):

…and then passing the same parameters through five different layers of your app?

In my latest video, I walk through a realistic Python example and show how to fix this mess using the Context Object Pattern.

I’ll start with the "before" version, refactor step by step, and explore:

How to group related dependencies using a context object
When this pattern helps and when it hurts
How to use Protocols to avoid too much coupling
Why separating high-level and low-level responsibilities makes your design better.

This is one of those patterns that’s easy to learn and immediately useful in real projects.Although... the pattern can also make things worse if you use it the wrong way - watch the video to learn more.

Have a great weekend!

Cheers,

Arjan

Why I’m Using uv Workspaces in All My Python Projects | Issue #76

Hi there, This week’s video is all about uv workspaces, and why they’ve completely changed the way I manage Python projects. In the video, I walk you through a real-world example: I build a CLI tool and a FastAPI API that both fetch and summarize news headlines using OpenAI. But the real lesson is in how the project is structured. I show you how to share a local package between apps, define common dependencies like openai or httpx only once. And you can manage everything using uv’s workspace...

Tired of if-elif chains? Here’s a cleaner way to write your code | Issue #75

Hi there, When I see an if-statement with multiple elifs in my code, it almost always triggers an investigation. Is there some way to rewrite this to make the logic simpler? Is there a chance that in the future I'll need to add even more complexity? If so, I'll try to redesign the code so that I don't need that chain of if-elif statements. In this week’s video, I cover a design pattern that helped me eliminate many of those chains from a project + at the same time made the code easier to...

Python 3.14 is here - and I love these features | Issue #74

Hi there, I just published a new video about Python 3.14, and no, it’s not just about the version number lining up with π (though that does make me feel more complete). The new release brings a bunch of improvements, but I decided to focus on the features I personally love and that I actually use in my day-to-day work. Here’s what I cover in the video: A small but beautiful improvement to exception syntax (fewer parentheses!) Native Zstandard compression with way better performance than gzip...
