Designing Extensible Python Applications with Plugin Architectures

🧠 Unlocking Extensibility: My Journey into Python Plugin Architectures 🚀 Why I Started Using This Early in my career, building applications often felt like crafting a monolithic sculpture. Every new feature, every slight alteration, meant chiseling directly into the core, often destabilizing parts that were already "finished." Adding new capabilities felt less like an addition and more like complex surgery, complete with all the associated risks.
