How do I use mixins in Python?

Mixins are a way to add functionality to classes in Python. They allow you to create reusable components that can be combined with other classes.

Can you give me an example of a mixin?

Sure! Here's a simple example: you can create a JsonMixin that adds a method to convert an object to JSON.

How would I implement that in a class?

You would define the mixin class with the JSON method, then inherit from it in your main class. For example:

class JsonMixin:
    def to_json(self):
        return json.dumps(self.__dict__)

class User(JsonMixin):
    def __init__(self, name, age):
        self.name = name
        self.age = age

What if I want to use multiple mixins?

You can simply inherit from multiple mixins in your class definition. Just ensure that there are no conflicting method names.
