How to Design an AWESOME Function Header in Python | Issue #19
Published over 1 year ago • 3 min read
Hi there,
This week’s video covers tips you probably haven’t considered—ones that can make or break your code and potentially save you hours of debugging. 🕵️♂️
Today I’m breaking down the art of designing function headers—because a good one makes your life 10x easier, while a bad one… well, you’ll wish you had known sooner.
👨💻 I’ll walk you through the essentials of function naming, and why using verbs in your function names can make all the difference. You’ll also learn how to streamline your function arguments to keep your code clean and readable, plus, I dive into type annotations to make sure your IDE catches issues before they become a problem. Enjoy the video and happy coding!
Cheers,
Arjan

Simplifying Python Data Validation
Real Python has just launched a new course on how to streamline data validation in Python using Pydantic! 🚀
Pydantic is one of the most popular libraries for data validation in Python (I’ve even created a few videos on it—check one out here).
This course covers everything from basic data validation to handling complex cases with custom validators. You’ll also learn to validate function arguments and manage application settings, all with minimal boilerplate. If you want to make your Python data handling more robust and efficient, this course is a fantastic resource. Dive into the details here.
Everything I Learned About Technical Debt
In his article, Erik Bernhardsson compares technical debt to real debt. He explains how you borrow resources now but pay back more later. 💸
Bernhardsson talks about the “interest rate” of technical decisions. He stresses how important it is to acknowledge and manage technical debt. Using practical examples, he illustrates when to take on or avoid technical debt, ensuring you make informed decisions that benefit your projects in the long run.

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...
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...
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...
