Use dependency injection patterns or frameworks like Dependency Injector . By passing services into classes rather than instantiating them inside, you make your code modular and easily mockable for unit tests. 7. Protocol and Structural Subtyping

| Pattern | Pythonic Implementation | When to Use | |---------|------------------------|--------------| | | Use module (module is singleton) or __new__ | Global config, logging | | Factory | Return class from function | Dynamic object creation | | Strategy | Pass function as argument | Algorithms interchangeable | | Decorator | @wraps + nested function | Add behavior without subclassing | | Context Manager | with + __enter__ / __exit__ | Resource cleanup (files, locks) |

In his book , Aaron Maxwell moves beyond beginner-level tutorials to focus on the "5% of programming knowledge" that accelerates the remaining 95%.
