"What are those class attributes for?"

Hello Everyone, I posted a different question regarding this code on stackoverflow and someone brought this question to my attention and I didn't know how to answer it . I was hoping someone can explain to me why Keenth decided to declare the sneaky and agile variables on the class level and in the init parameters.

Here is his question "Which raises another point: What are those class attributes for? If you wanted them to provide default values, you've already got default values on the initializer parameters for that, so they're useless.

If you wanted them to provide values during initialization, then they're potentially wrong, so they're worse than useless. If you need to have a self.sneaky before calling Character.init, the way to do that is simple: just move self.sneaky = sneaky up before the super() call.

In fact, that's one of the strengths of Python's "explicit super" model. In some languages, like C++, constructors are always called automatically, whether from inside out or outside in. Python forcing you to do it explicitly is less convenient, and harder to get wrong—but it means you can choose to do your setup either before or after the base class gets its chance (or, of course, a little of each), which is sometimes useful."

here is the code in question

class Character:
    def __init__(self, name="", **kwargs):
        if not name:
            raise ValueError("'name' is required")
        self.name = name

        for key, value in kwargs.items():
            setattr(self, key, value)


class Agile:
    agile = True

    def __init__(self, agile=True, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.agile = agile


class Sneaky:
    sneaky = True

    def __init__(self, sneaky=True, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.sneaky = sneaky


class Thief(Agile, Sneaky, Character):
    def pickpocket(self):
    return self.sneaky and bool(random.randint(0, 1))


parker = Thief(name="Parker", sneaky=False)
