What is Abstract Base Class In Python?
An Abstract Base Class (ABC) in Python is a class that cannot be instantiated on its own and serves as a blueprint for other classes. It defines a set of methods that must be created within any subclass derived from the ABC, ensuring a consistent interface. ABCs are part of the `abc` module, which provides decorators like `@abstractmethod` to declare abstract methods. By using ABCs, developers can enforce certain behaviors in subclasses, promoting code reusability and design clarity. This mechanism is particularly useful in large applications where multiple classes share common functionality but implement it differently.
