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...
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...

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...
