python 面向对象类与类之间的关系

class Elephant:
    def __init__(self,name):
        self.name = name
    def open(self,ref):
        print("冰箱,开门吧")
        ref.open_door()
    def close(self,ref):
        print("冰箱关门吧")
        ref.close_door()
    def enter(self):
        print("进冰箱装自己")
class Fridge:

def init(self):

pass

def open_door(self):

print("冰箱打开了门")

def close_door(self):

print("冰箱关上了门")
E=Elephant("tony")

F1=Fridge()

E.open(F1)

E.enter()

E.close(F1)

class Boy:
    def __init__(self,name,character,girlfriend=None):
        self.name = name
        self.character = character
        self.girlfriend = girlfriend
    def xiangqin(self,girl):
        self.girlfriend = girl
    def eat(self):
        if self.girlfriend:
            print("吃东西好难,吃啥都不对")
        else:
            print("单身狗,狗粮够吗")
class Girl:
    def __init__(self,boyfriend):
        self.name = name

g = Girl("排骨精","八戒")

b.xiangqin(g)

b.eat()

        self.name = name
        self.address = address
        self.phone = phone
        self.__teach_list = []
    def zhaopin(self,t):
        self.__teach_list.append(t)
    def display(self):
        for el in self.__teach_list:
            print(el.name,el.hobby)
class Teacher:

def init(self,gender,salary,hobby,school):

self.name = name

self.gender = gender

self.salary = salary

self.hobby = hobby

self.school = school
oldboy_bj = School("北京老男孩","美丽富饶的沙河","10086")

oldboy_sh = School("北京老男孩， 上海分校","上海浦东","10010")

oldboy_sz = School("北京老男孩， 深圳分校（骑士计划)","南山区","10000")
t1 = Teacher("配齐","男",200000,"上课",oldboy_bj)

t2 = Teacher("太白",150000,"开车",oldboy_bj)

t3 = Teacher("Eggon",123456,"钻研技术",oldboy_sh)

t4 = Teacher("高鑫","女",45678,"相夫教子",oldboy_sz)

t5 = Teacher("日天",666,"看天",oldboy_sz)
oldboy_bj.zhaopin(t1)

oldboy_bj.zhaopin(t2)

oldboy_bj.display()
oldboy_sh.zhaopin(t3)

oldboy_sz.zhaopin(t4)

class Base:
    def __init__(self,num):
        self.num = num
    def func1(self):
        print(self.num)
        self.func2()
    def func2(self):
        print(111,self.num)
class Foo(Base):
    def func2(self):
        print(222,self.num)
lst = [Base(1),Base(2),Foo(3)]
for obj in lst:
    obj.func1()

总结:

• self在访问方法的顺序: 永远先找自己的,自己的找不到再找父类的.?
• self就是你访问方法的那个对象,先找自己,然后在找父类的.?

4. 类中的特殊成员
