设置嵌套属性时未执行Python setter

class Address:
    def __init__(self, city, street):
        self._city = city
        self._street = street

    @property
    def city(self):
        return self._city

    @city.setter
    def city(self, value):
        # 执行一些额外的逻辑或验证
        self._city = value

class Person:
    def __init__(self, name, address):
        self._name = name
        self._address = address

    @property
    def name(self):
        return self._name

    @name.setter
    def name(self, value):
        # 执行一些额外的逻辑或验证
        self._name = value

    @property
    def address(self):
        return self._address

    @address.setter
    def address(self, value):
        # 执行一些额外的逻辑或验证
        self._address = value

# 创建对象
address = Address("Beijing", "Main Street")
person = Person("John", address)

# 设置嵌套属性时调用setter方法
person.address.city = "Shanghai"

# 打印属性值
print(person.address.city)  # 输出：Shanghai
