Pythonic Interfaces The secret to building maintainable, quality code
summary
Defines interfaces as method blueprints and demonstrates enforcing them to catch missing methods and wrong signatures earlier. Uses stdlib introspection — inspect.signature, inspect.isdatadescriptor, MRO navigation plus isgeneratorfunction/iscoroutinefunction — to compare method names, signatures, descriptors and decorators. Compares enforcement options: abc (checks at instantiation) versus early checks on import/class creation via the implements decorator or python-interface/zope.interface. Concludes Python 3 typing and inspect make richer, earlier enforcement practical.
