[July 2025] Python Monthly Newsletter 🐍

Welcome to the 68th issue of Python Monthly!

If it’s your first time here, welcome, I like you already. If you want the full back story on this monthly newsletter, head here.

The quick version: I curate and share the most important Python articles, news, resources, podcasts, and videos.

Think the Pareto Principle (80/20 rule) meeting the Python world. I give you the 20% that will get you 80% of the results.

If you're a long time reader, welcome back old friend.

Alright, let's not waste any valuable time and jump right into this month's updates.

Here's what you missed in June 2025 as a Python Developer…

Useless Design Patterns 🎀

Search for “design patterns in Python” and you’ll be rewarded with a parade of tutorials showing off how to faithfully re-implement Gang of Four patterns — complete with class diagrams, factory hierarchies, and enough boilerplate to heat a small village.

They’ll make you feel like you’re writing “serious” code. Smart. Professional. Enterprise-ready.

But here’s the problem: most of these patterns solve problems Python doesn’t have.

Django turns 20 🪅

Happy birthday to Django which is now outside of its teenage grumpy years. That's it... nothing else to report.

CPython’s JIT Compiler 🗜

This is worth the read. A deep dive in to the Just-in-Time compiler that this author has been working on for CPython. It will give you a great understanding for how things work under the hood.

330× faster Python 🏃

An insightful article showing you the 4 ways you an speed up your Python easily.

1. Efficiency: Getting rid of wasteful or repetitive calculations. (loops)
2. Compilation: Using a compiled language, and potentially working around the compiler’s limitations.
3. Parallelism: Using multiple CPU cores.
4. Process: Using development processes that result in faster code.

Crypto 101 🔑

Before you think this is about buying lambos and going to the moon while doing absolutely zero work, this is about cryptography.

Crypto 101 is an introductory course on cryptography, freely available for programmers of all ages and skill levels. It's very technical and very informative. It's also not gambling.

Mental Models For Engineers 📔

How do you become a senior engineer? What distinguishes these engineers — the senior ones in spirit, not just in title — isn’t a fixed set of knowledge, tools, or even experience in years.

It’s how they see. The lens they use to model the complexity of systems, tradeoffs, and people.

If you could look inside their head, you’d find three dominant forces shaping their mental architecture: focus, friction and feedback.

AI Makes You Unproductive 🚧

Interesting study shows that we overestimate productivity gains from using AI tools.

This is worth a thought.
