Summary
We began the book with the foundational design principles that developers should follow for writing maintainable, flexible, and robust software. From encapsulating what varies to favoring composition, programming to interfaces, and aiming for loose coupling, these principles provide a strong foundation for any Python developer.
As you’ve seen, these principles are not just theoretical constructs but practical guidelines that can significantly improve the quality of your code. They set the stage for what comes next: diving deeper into more specialized sets of principles that guide object-oriented design.
In the next chapter, we will delve into the SOLID principles, a set of five design principles aimed at making software designs more understandable, flexible, and maintainable.
