property装饰器

1.property装饰器

property装饰器就是把方法伪装成属性给对象调用
eg
  class Student():
    __school = 'SH'  # _Student__school  => _类名__属性名

    def __init__(self, name, age):
        self.__name = name
        self.age = age

    def __tell_info(self):  # _Student__tell_info  => _类名__函数名
        print('name: %s, age: %s' % (self.__name, self.age))

    @property  # 把方法伪装成属性
    def name(self):
        return "name:%s" % self.__name

    @name.setter
    def name(self, v):
        if type(v) is not str:
            print('数据类型不合法')
        # if isinstance(v, str):
            return
        self.__name = v

    @name.deleter
    def name(self):
        print('不让删')

stu = Student('ly', 18)
print(stu.get_name())

stu.name = 123
print(stu.name)

del stu.name
