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...
