Go for Pythonistas: What You Need to Know | Issue #40

Published about 1 year ago • 2 min read

Hi there,

​

Python is simple but frustrating. Rust is powerful but strict. And then there’s Go—fast, modern, and surprisingly easy to use. I put it to the test against Python and Rust, and what I found blew my mind. 🤯
​

Go nails concurrency, has built-in tools (no pytest or flake8 needed), and in some cases… it even beats Rust in performance. Yes, really. I built a REST API, ran benchmarks, and compared everything from syntax to error handling.
​

Is Go the perfect balance between Python’s simplicity and Rust’s power? Watch this week’s video to find out! 🚀

​

Cheers,

Arjan

How to Deal With Missing Data in Polars

Polars is fast and efficient, but how does it handle missing data? 🤔

A new Real Python article explores how Polars defines "missing," how it compares to Pandas, and the best ways to fill, drop, and detect null values. If you're working with data pipelines, this is a must-read! 👉 Check out here.

Top Python Libraries of 2024

Python’s ecosystem is always evolving, and staying ahead means knowing which tools are shaping the industry.

Tryolabs recently highlighted some of the most impactful Python libraries from 2024—many of which are set to play an even bigger role this year. Here are the top Python libraries in 2024. 🚀

# Community

Recently in our Discord server, an interesting discussion sparked around a video by Dave Farley about critical warning signs in software projects.

Here are a few red flags that stood out:

🚩 Rigid planning – Overplanning makes teams resistant to change, even when it’s obvious the plan isn’t working.

🚩 The “hero developer” trap – Relying on a few rock stars instead of building resilient teams.

🚩 Big risky changes – Instead of “Many More Much Smaller Steps” (MMMSS), teams often take big leaps that increase failure rates.

🚩 Strict control policies – Some teams require approval just to add a new class! This often happens in large companies with poor encapsulation, where changing one system risks breaking everything.

These discussions remind me how good software design can mitigate many of these issues. Functional programming, strong modularization, and clear feedback loops can help avoid these pitfalls.

Code can be correct and still be unpleasant to read. A lot of software design isn’t about what the code does but about how clearly it communicates the sequence of ideas behind it. In this week’s video, I explore the Fluent Interface pattern by refactoring a small animation engine in Python. I start with a clunky but functional API, then gradually reshape it until defining an animation reads almost like a sentence: move, rotate, scale, fade. Enjoy this deep dive into API design, readability,...

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...
