如何在构造函数中使用setter？

class Person:
    def __init__(self, name, age):
        self._name = None
        self._age = None
        self.name = name
        self.age = age

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

    @name.setter
    def name(self, value):
        # 在setter中可以添加属性验证或处理逻辑
        if not isinstance(value, str):
            raise ValueError("Name must be a string.")
        self._name = value

    @property
    def age(self):
        return self._age

    @age.setter
    def age(self, value):
        # 在setter中可以添加属性验证或处理逻辑
        if not isinstance(value, int) or value < 0:
            raise ValueError("Age must be a positive integer.")
        self._age = value

# 创建Person对象并设置属性值
person = Person("Alice", 25)
print(person.name)  # 输出: Alice
print(person.age)  # 输出: 25

# 尝试设置非法属性值，将会抛出异常
person.name = 123  # 抛出异常: ValueError: Name must be a string.
person.age = -10  # 抛出异常: ValueError: Age must be a positive integer.
