This Is How Marie Kondo Sets up Her Pytest | Issue #45

Published 10 days ago • 2 min read

Hi there,

​

Be honest—how much do you enjoy writing tests? If the answer is “not at all,” chances are your setup is too complicated.

​

In this week’s video, I show you how to set up pytest the right way—step by step, with zero fluff. I go from zero tests to a fully working pytest setup, covering advanced tricks along the way (including one almost nobody knows about). 🧪

​

By the end, your tests will be clean, fast, and easy to maintain. No more fighting with pytest configurations.

​

If your test suite could use a little Marie Kondo magic, watch the video now. 🎥

​

Happy testing!

​

Cheers,

Arjan

The Beauty of Ugly Code

We all strive to write clean, elegant code—but what if ugly code is sometimes the right choice? Armin Ronacher (creator of Flask) recently shared a thought-provoking article on why ugly code isn’t always bad. In fact, it can be a pragmatic, necessary response to real-world constraints.💡

His post challenges conventional wisdom, reminding us that practicality beats purity when it comes to software design. 💬 Read the full article here.

Hi there, Did you know Python has over 60 built-in functions, and you can use them without importing a single module? This week I explore 12 powerful built-ins that can make your code more efficient and Pythonic. Some of these are absolute game-changers, and yet, I rarely see them used! In this video, you’ll learn how to: ✅ Use filter() and map() for cleaner data processing ✅ Pair iterables like a pro with zip() ✅ Turn any function into an iterator with iter(callable, sentinel) (yes, that’s a...
