Question

from abc import ABCMeta, abstractmethod

class Employee(object, metaclass=ABCMeta):

    def __init__(self, name):
        self._name = name

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

    @abstractmethod
    def get_salary(self):
        pass

class Salesman(Employee):

    def __init__(self, name, sales=0):
        super().__init__(name)
        self._sales = sales

    @property
    def sales(self):
        return self._sales

    @sales.setter
    def sales(self, sales):
        self._sales = sales if sales > 0 else 0

    def get_salary(self):
        return 1200.0 + self._sales * 0.05

def main():
    emps = Salesman('aa')
    emps.sales = int(input('请输入销售额：'))
    print(emps.get_salary())

if __name__ == '__main__':
    main()

为什么把self._name = name 改为self.name = name;  self._sales = sales 改为 self.sales = sales 后就会报错呢？

 

Answer 1

class Employee(object):
    def __init__(self, name):
        self.name = name

    @property
    def name1(self):
        return self.name

    def get_salary(self):
        pass


class Salesman(Employee):
    def __init__(self, name, sales=0):
        super().__init__(name)
        self.sales = sales

    @property
    def sales(self):
        return self._sales

    @sales.setter
    def sales(self, sales):
        self._sales = sales if sales > 0 else 0

    def get_salary(self):
        return 1200.0 + self._sales * 0.05

def main():
    emps = Salesman('aa')
    emps.sales = int(input('请输入销售额：'))
    print(emps.get_salary())

if __name__ == '__main__':
    main()

你的Employee有个方法叫name，把方法名改一下就好了
