10 Python Features You’re Not Using (But Really Should)

10 Python Features You’re Not Using (But Really Should) | Issue #90

Published 4 days ago • 1 min read

Have you ever looked at a Python script and thought:

“Why is this slow? The logic is trivial.”

Very often, the problem isn’t what your code does, but how often it does expensive work.

In this week’s video, I start with a deliberately inefficient example: parsing a large CSV file multiple times. From there, I use it as a vehicle to introduce 10 powerful Python features that many developers either don’t know about or don’t know when to apply.

I look at things like:

• caching expensive computations

• safer ways to work with immutable data

• clearer control flow for complex business rules

• better tools for resource management and async context

All of them are part of Python’s standard library. No frameworks. No dependencies. Just better use of the language you already have.

Have a great weekend!

Cheers,

Arjan

This Pattern Is Horrifyingly Overengineered | Issue #89

I almost didn’t publish this week’s video. It’s about the Specification design pattern, and if I’m honest, the final version of the code scared me a little. It’s complex, abstract, and in many cases… absolutely overengineered. But there’s a reason I still decided to share it. In the video, I explore how the Specification pattern tackles a very real problem: business rules duplicated across different parts of a system, slowly drifting apart and becoming harder to change safely. Is this...

7 Things You Didn’t Know Dataclasses Could Do | Issue #88

Most Python developers know dataclasses. Or at least… they think they do 🙂. You add @dataclass, define a few fields, and enjoy writing less boilerplate. But dataclasses hide a lot more power than most people realize and some of that power can quietly bite you if you don’t understand what’s really going on. In this week’s video, I walk through 7 lesser-known dataclass features that make your code safer, clearer, and easier to maintain. I start with common pitfalls like mutable defaults, then...

Stop Prompting, Start Designing | Issue #87

AI can write code now. But you already knew that :). If you’ve tried using AI seriously, you’ve probably noticed something: the code works (kind of) and then slowly turns into a mess. In this week’s video, I show why prompting alone isn’t enough and why software design is becoming more important, not less, in an AI-driven world. I walk through a real interaction with an AI coding assistant and show how thinking in terms of responsibilities, structure, and system boundaries completely changes...
