What are interfaces in Python's object-oriented programming?

Can you explain what interfaces are in Python's object-oriented programming?

In Python, an interface is a set of methods that a class must implement, defining a contract for behavior.

How do I create an interface in Python?

You can create an interface using abstract base classes (ABCs) from the abc module. Define abstract methods that subclasses must implement.

Can you give me an example of an interface in Python?

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'
