Hi there, When I see an if-statement with multiple elifs in my code, it almost always triggers an investigation. Is there some way to rewrite this to make the logic simpler? Is there a chance that in the future I'll need to add even more complexity? If so, I'll try to redesign the code so that I don't need that chain of if-elif statements. In this week’s video, I cover a design pattern that helped me eliminate many of those chains from a project + at the same time made the code easier to...
Hi there, I just published a new video about Python 3.14, and no, it’s not just about the version number lining up with π (though that does make me feel more complete). 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...
