Summary
In this chapter, we explored the SOLID principles and their application in Python to create clean, maintainable, and flexible architectures. We learned how each principle contributes to robust software design:
- SRP for creating focused, cohesive classes
- OCP for extending behavior without modification
- LSP for ensuring well-formed, substitutable abstractions
- ISP for designing targeted, client-specific interfaces
- DIP for structuring dependencies to maximize flexibility
These principles are crucial for developing Python applications that can evolve with changing requirements, resist software entropy, and remain clear as systems grow in complexity. They form the foundation of Clean Architecture, enabling us to create more modular, testable, and adaptable code.
In the next chapter, we’ll explore how to leverage Python’s type system to further enhance the robustness and clarity of our Clean Architecture designs. You’...
