Python Abstract Base Classes ABC
Article Introduction:ABC is a module in Python used to define abstract base classes. It forces subclasses to implement specific behaviors through abstract methods. When using it, you need to import ABC and abstractmethod from the abc module, inherit ABC and use @abstractmethod to mark the methods that must be rewritten; abstract classes can contain ordinary methods and abstract methods, and subclasses must implement all abstract methods before they can be instantiated; it is suitable for scenarios that unify interfaces, share part of logic, and improve the clarity of code structures, such as plug-in systems, framework design, and multi-data source processing.
