What are abstract base classes in Python?
Abstract Base Classes (ABCs) in Python are a way to define common interfaces for a group of related classes.
How do I create an abstract base class?
You can create an ABC by inheriting from abc.ABC
and using the @abstractmethod
decorator for methods.
Can you give me an example of using an abstract base class?
Sure! Here's a simple example:
from abc import ABC, abstractmethod
class Animal(ABC):
@abstractmethod
def sound(self):
pass
class Dog(Animal):
def sound(self):
return 'Bark'
class Cat(Animal):
def sound(self):
return 'Meow'
