如何在子类中访问超类中的私有成员变量？

class SuperClass:
    def __init__(self):
        self.__private_var = "Private Variable"

    def get_private_var(self):
        return self.__private_var

class SubClass(SuperClass):
    def __init__(self):
        super().__init__()

    def access_private_var(self):
        return self.get_private_var()

sub_class = SubClass()
print(sub_class.access_private_var())

class SuperClass:
    def __init__(self):
        self.__private_var = "Private Variable"

class SubClass(SuperClass):
    def __init__(self):
        super().__init__()

    def __getattr__(self, name):
        if name == "private_var":
            return self._SuperClass__private_var
        raise AttributeError(f"'{self.__class__.__name__}' object has no attribute '{name}'")

sub_class = SubClass()
print(sub_class.private_var)
