Improve maintainability, structure, and scalability.
Quick Answer
Python design patterns: Singleton (one instance - use module-level variable or metaclass), Factory (create objects without specifying exact class), Observer (publish-subscribe with callbacks), Strategy (swap algorithms - pass functions), Decorator (functools.wraps), Command (encapsulate actions as objects). Python's duck typing and first-class functions make many patterns simpler than in Java/C++.
