python 单继承的实现

第一类单继承的实现：
from person import Person
from student import Student
from worker import Worker

per = Person("aa", 1, 2)
stu = Student("tom", 18, 12345, 110)
print(stu.name, stu.age)
stu.run()
print(stu.stuId)
#print(stu.__money)私有属性
print(stu.getMoney())  #通过继承过来的共有方法访问私有属性
#stu.stuFunc()

wor = Worker("lilei", 20, 111)
print(wor.name, wor.age)
wor.eat("apple")

print(per.getMoney()

第二类person：

class Person(object):
    def __init__(self, name, age, money):
        self.name = name
        self.age = age
        self.__money = money

    def setMoney(self, money):
        self.__money = money
    def getMoney(self):
        return self.__money

    def run(self):
        print("run")

    def eat(self, food):
        print("eat " + food)

第三类student：

from person import Person

class Student(Person):
    def __init__(self, name, age, money, stuId):
        #调用父类中的__init__
        super(Student, self).__init__(name, age, money)
        #子类可以有一些自己独有的属性
        self.stuId = stuId

    def stuFunc(self):
        print(self.__money)

第四类worker：

from person import Person

class Worker(Person):
    def __init__(self, name, age, money):
        #调用父类中的__init__
        super(Worker, self).__init__(name, age, money)
