10 Tips to Become REALLY Good at Python | Issue #37

Published 9 months ago • 2 min read

Hi there,

​

Let’s talk about Python—the language we all love. ❤️ You might think you know your way around it, but even senior developers can fall into common traps or miss out on some of its best features.

​

In this week’s video, I break down 10 tips that will make your code cleaner, faster, and more Pythonic.

​

For example, comprehensions are not just for lists—you can use them for sets, dictionaries, and even generators. And if you’re not using f-strings yet… well, you’re missing out on a lot of readability and power!

​

The last tip, though, is my personal favorite—it’s one I wish more developers knew when I review their code.

​

Cheers,

Arjan

Generative AI Is Not Going to Build Your Team

Generative AI tools like ChatGPT and GitHub Copilot can supercharge productivity, but let’s be real—they won’t replace the creativity, collaboration, or critical thinking of a skilled engineering team. 🚀

As this Stack Overflow article points out, AI can’t handle complex team dynamics or bring that essential human touch to innovation. Think of AI as your assistant, not your substitute—a powerful sidekick that helps you level up, not take over. Read the full article here.

Insane and Fun Facts About SQLite

SQLite is the most widely deployed database engine in the world, powering over a trillion active databases. It stands out from most software by being in the public domain, allowing unrestricted use.

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...

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...
