Design patterns in Python improve code maintainability by enforcing KISS, SRP, and composition over inheritance. They help architects and engineers separate concerns, yielding modular, testable code that prevents duplicated logic and tangled architectures.

Use composition over inheritance in Python when designing new components that require flexible, testable architectures. This approach enables you to build cohesive services by assembling small, focused classes rather than relying on rigid inheritance hierarchies.

Apply SRP and KISS to improve Python code readability by reframing modules into small, focused functions and classes with clear responsibilities. This creates simple, focused components that are easier to test and maintain.

The best way to introduce abstractions in legacy Python code is to evaluate whether they enforce separation of concerns and yield modular, testable components. Apply established design patterns to untangle duplicated code and improve overall maintainability.

Applying design patterns to Python does not require external dependencies. The approach focuses on structural improvements like composition over inheritance and SRP, allowing you to refactor modules and design components natively.
