Getting Started with Agentic AI: Concepts, Terminology, and a Python Hello World

AI agents were still in a nascent stage when I first started hearing the term ‘AI agents’ , it felt like one of those concepts which everyone nodded to but very few could clearly explain. Today, almost every other engineer seems to be building, experimenting with, or at least talking about agentic AI in some form. What was once a vague concept has quickly become a hands-on playground for technologists.
