有2个类,我如何在上面的类中使用下面的类的对象？

class ClassA:
    def __init__(self):
        self.attribute_a = "Attribute A"

class ClassB(ClassA):
    def __init__(self):
        super().__init__()
        self.attribute_b = "Attribute B"

    def use_class_a_object(self):
        print(self.attribute_a)

class_b_object = ClassB()
class_b_object.use_class_a_object()

class ClassA:
    def __init__(self):
        self.attribute_a = "Attribute A"

class ClassB:
    def __init__(self):
        self.class_a_object = ClassA()
        self.attribute_b = "Attribute B"

    def use_class_a_object(self):
        print(self.class_a_object.attribute_a)

class_b_object = ClassB()
class_b_object.use_class_a_object()
