SOLID Principles in Python

Stop memorizing SOLID and start applying it.

You’ve heard of the SOLID principles. Maybe you’ve even recited them in an interview. But can you spot a real violation in a legacy codebase? Can you fix it without over-engineering?

SOLID Principles in Python cuts through abstract theory and toy examples. Instead, you’ll work with ShopFlow, a minimal but realistic order-processing system built from the ground up using Clean Architecture, and you'll refactor it step by step using each of the five SOLID principles:

- Single Responsibility
- Open/Closed
- Liskov Substitution
- Interface Segregation
- Dependency Inversion
