🧭 What is this course?
Anyone can make code that works. The real skill is making code that's easy to read, easy to change, and hard to break. That's software architecture & design — the craft of building programs that grow without turning into a tangled mess.
You'll learn how professional engineers organize big programs: clean naming, objects, the famous SOLID principles, reusable design patterns, modules, and testing. Each lesson has a 📖 Description and a 🎮 Practice tab with real Python.
👉 Recommended: finish Python Basics first — you'll use functions, lists, and dictionaries everywhere here.
Clean Code
Good names, small functions, and code that reads like a story. The foundation of everything.
Start here ✨ 2Objects & Classes
Bundle data and behavior together with classes — the building blocks of big programs.
OOP 3SOLID Principles
Five famous rules that keep object-oriented code flexible and easy to extend.
Principles 4Design Patterns
Reusable solutions to common problems — factory, strategy, and observer made simple.
Patterns 5Modules & Structure
Split a program into tidy pieces. Separation of concerns and clean dependencies.
Structure 🏆Testing & TDD
Prove your code works with automated tests — and let tests guide your design.
