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...

Hi there, You’ve probably noticed this by now: LLM prototypes are easy to build. But as soon as you try to turn them into actual production LLM systems… a lot more goes into it. In this week’s video, I walk through how to structure AI agents in Python using design patterns like Chain of Responsibility, Observer, and Strategy. I’ll build a fully functional travel assistant using Pydantic AI and explore how to make your agent pipelines more maintainable, testable, and modular. Hope you enjoy...

Hi there, I have to admit, I often forget how powerful the Python standard library is. Whenever I'm working on some project, I have to remind myself to consider whether something I need is already there, ready for me to use. So, in this week’s video, I’m looking at 10 of the most useful and underrated modules in Python’s standard library, including pathlib, heapq, graphlib, and more. These tools can help you write cleaner, faster, and more maintainable code without adding a single dependency....
