def mixin_behavior(cls):
    class Mixin:
        def extra_method(self):
            return "Extra behavior"
    return type(cls.__name__, (cls, Mixin), dict(cls.__dict__))

class Original:
    def original_method(self):
        return "Original behavior"

Enhanced = mixin_behavior(Original)
instance = Enhanced()
print(instance.original_method())  # Output: Original behavior
print(instance.extra_method())    # Output: Extra behavior

You can use metaclasses to dynamically create and modify classes.
