Refactoring Python code for maintainability requires applying core design patterns like SRP and KISS to clarify structure. This approach untangles complex modules by evaluating abstractions and choosing composition over inheritance where appropriate.

Implementing composition over inheritance in Python means building classes from smaller, dedicated components rather than deep hierarchies. This design pattern improves code adaptability and testability by keeping responsibilities separated and reducing structural rigidity.

Introduce abstractions in Python architecture when designing new components or refactoring tangled code, avoiding premature optimization. Apply principles like KISS to ensure abstractions solve concrete structural problems without overcomplicating the codebase.

The Single Responsibility Principle (SRP) in Python projects ensures each class or module handles one specific function. Applying SRP improves code readability and makes individual modules easier to test and scale as the project grows.

Using design patterns like composition over inheritance and SRP makes Python code easier to test by decoupling dependencies and isolating functionality. These patterns provide clear structure, allowing unit tests to target specific behaviors without complex setup.

The main limitation of using design patterns in Python is the risk of premature optimization and overcomplicating simple tasks. Applying patterns without evaluating actual architectural needs reduces code readability, directly contradicting principles like KISS.
