What are the best practices for using interfaces in Python?

In Python, interfaces can be implemented using abstract base classes (ABCs). Best practices include defining clear methods, using type hints, and ensuring that your interfaces are easy to understand and implement.

Can you give an example of 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'

How do I ensure my interface is user-friendly?

To ensure your interface is user-friendly, provide clear documentation, use descriptive method names, and keep the interface minimal by only including essential methods.

What are some common mistakes to avoid?

Common mistakes include overcomplicating the interface, not providing enough documentation, and failing to follow the single responsibility principle.
