如何将Class属性的每个属性和方法设置为Class的属性和方法？

class Class:
    def __init__(self):
        self._attribute = None

    @property
    def attribute(self):
        return self._attribute

    @attribute.setter
    def attribute(self, value):
        self._attribute = value

    @staticmethod
    def static_method():
        print("This is a static method.")

    @classmethod
    def class_method(cls):
        print("This is a class method.")
        print("Class attribute:", cls._attribute)

    def instance_method(self):
        print("This is an instance method.")
        print("Instance attribute:", self._attribute)


# 创建Class类的实例
obj = Class()

# 访问和修改属性
obj.attribute = "Hello"
print(obj.attribute)

# 调用静态方法
Class.static_method()

# 调用类方法
Class.class_method()

# 调用实例方法
obj.instance_method()
