When should I use interfaces in Python?

In Python, interfaces can be used to define a contract for classes. They are useful when you want to ensure that different classes implement certain methods.

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

Sure! You can use the abc module to create an interface. For example:

from abc import ABC, abstractmethod

class Animal(ABC):
    @abstractmethod
    def sound(self):
        pass

class Dog(Animal):
    def sound(self):
        return 'Bark'

What are the benefits of using interfaces?

Using interfaces promotes code reusability and flexibility. It allows you to define a common API for different classes, making it easier to manage and extend your code.

Are there any downsides to using interfaces?

One downside is that they can add complexity to your code. If not used judiciously, they may lead to over-engineering, especially in smaller projects.
