        self.__name = name
        self.__salary = salary

    @property
    def salary(self):
        return self.__salary

    @salary.setter  # x.setter这里要和方法名相同
    def salary(self, salary):
        if 1000 < salary < 20000:
            self.__salary = salary
        else:
            print('录入错误')
emp1 = Employee('jack', 2000)
