Python Playground

class Loggable:
    def log(self, message):
        print(f"[{self.__class__.__name__}] {message}")

class Serializable:
    def to_dict(self):
        return {k: v for k, v in self.__dict__.items()
                if not k.startswith("_")}

class User(Loggable, Serializable):
    def __init__(self, name, email):
        self.name = name
        self.email = email

u = User("Alice", "alice@example.com")
u.log("created")
print(u.to_dict())

# Method Resolution Order
print(User.__mro__)

Python uses C3 linearization for MRO. Multiple inheritance lets you compose behaviors from several base classes, but order matters.

Challenge

Try modifying the code above to explore different behaviors. Can you extend the example to handle a new use case?
