A Better Place to Put Your Python Virtual Environments
By Ahmed Lemine on 7 March 2024
Virtual environments are vital if you’re developing Python apps or just writing some Python scripts. They allow you to isolate different app requirements to prevent conflicts and keep your global OS environment clean. This is super important for many reasons. The most obvious one is requirements isolation. Let’s say that you’re working on two different… Continue reading A Better Place to Put Your Python Virtual Environments
Build a route planner for maps using Python
By Judith Vockenroth on 7 March 2024
In this article I use the metric system, where 1 meter = 3.28 feet. I also talk about highways. Here I use the definition in British English, where highway refers to any path with a public right of access. We are all familiar with the existence of route planners like google maps or OpenStreetMaps (OSM),… Continue reading Build a route planner for maps using Python

Elevate Your Python: Harnessing the Power of Abstract Base Classes (ABCs)
By Bob Belderbos on 26 January 2024
Introduction One cool object-oriented programming (OOP) technique / pattern is enforcing consistent interfaces. In Python you can use Abstract Base Classes (ABCs) for that. 🐍 Using ABCs ensures that all subclasses implement the required methods. This can make it easier to maintain and extend the existing code base. Update Feb 2024: you can also leverage… Continue reading Elevate Your Python: Harnessing the Power of Abstract Base Classes (ABCs)
