The new release brings a bunch of improvements, but I decided to focus on the features I personally love and that I actually use in my day-to-day work. Here’s what I cover in the video: A small but beautiful improvement to exception syntax (fewer parentheses!) Native Zstandard compression with way better performance than gzip...
Hi there, When you start a new Python project, it often begins as a single file. Before you know it, that file turns into a tangle of routes, configs, and ad-hoc fixes. Scaling that into something a team can maintain is tough. In my latest video, I show you the anatomy of a scalable Python project. We’ll cover folder structure, config management, logging, testing, and how to set up pyproject.toml, .python-version, Docker, and docker-compose for smooth local and production environments. I’ll...
Hi there, You’ve probably heard of the SOLID principles... and maybe even felt guilty for not applying them more. But how useful are they really when you’re writing Python? In my latest video, I take a simple but realistic example and implement it three ways: A messy, all-in-one class that gets the job done A cleaner, class-based version that follows SOLID principles A lightweight, functional approach that may be more Pythonic In the end, the important thing is to understand where design...
