    Abstract Base Classes (ABCs) in Python provide a way to define abstract classes and enforce their interface on their subclasses. This is useful for ensuring that derived classes implement specific methods, providing a standardized way to test whether an object adheres to a given specification.

    Defining Abstract Base Classes

    To define an abstract base class in Python, you use the abc module. This module provides the ABC class and the ABCMeta metaclass. The ABC class is a helper class that has ABCMeta as its metaclass, allowing you to create an abstract base class by simply deriving from ABC.

    from abc import ABC, abstractmethod

    class MyABC(ABC):
    @abstractmethod
    def my_method(self):
    pass
    Copied!

    In this example, MyABC is an abstract base class with an abstract method my_method. Any subclass of MyABC must implement my_method to be instantiated.

    Using Abstract Methods

    Abstract methods are defined using the @abstractmethod decorator. A class that has a metaclass derived from ABCMeta cannot be instantiated unless all of its abstract methods are overridden.

    What is abstract base class (ABC) in Python?
    Abstract Base Class (ABC) allow us to define a blueprint for other classes. This blueprint ensures that any class deriving from the Abstract Base Class (ABC) implements certain methods by providing a consistent interface.
