5.组合

6.继承
1 class Dad: 2 '这个是爸爸类' 3 money=10 4 def __init__(self,name): 5 print('爸爸') 6 self.name=name 7 def hit_son(self): 8 print('%s 正在打儿子' %self.name) 9 10 class Son(Dad): 11 money = 1000000000009 12 def __init__(self,name,age): 13 self.name=name 14 self.age=age 15 16 def hit_son(self): 17 print('来自儿子类') 18 # print(Son.money) 19 # Son.hit_son(Son('andy',12)) 20 # print(Dad.__dict__) 21 # print(Son.__dict__) 22 s1=Son('alex',18) 23 # s1.hit_son() 24 print(s1.money) 25 print(Dad.money) 26 print(s1.name) 27 print(s1.money) 28 print(s1.__dict__) 29 s1.hit_son()
7.接口继承
1 import abc 2 class All_file(metaclass=abc.ABCMeta): 3 @abc.abstractmethod 4 def read(self): 5 pass 6 7 @abc.abstractclassmethod 8 def read1(self): 9 pass 10 11 @abc.abstractmethod 12 def write(self): 13 pass 14 15 @abc.abstractclassmethod 16 def write1(self): 17 pass 18 19 class Disk(All_file): 20 def read(self): 21 print('disk read') 22 23 def write(self): 24 print('disk write') 25 26 class Cdrom(All_file): 27 def read(self): 28 print('cdrom read') 29 30 def write(self): 31 print('cdrom write') 32 33 34 class Mem(All_file): 35 def read(self): 36 print('mem read') 37 38 def write(self): 39 print('mem write') 40 41 class Mem1(All_file): 42 def read(self): 43 print('mem read') 44 45 def write(self): 46 print('mem write') 47 # 48 m1=Mem1() 49 m1.read() 50 m1.write()
8.继承顺序
1 #coding:utf-8 2 class A: 3 def test(self): 4 print('A') 5 pass 6 class B(A): 7 # def test(self): 8 # print('B') 9 10 pass 11 class C(A): 12 def test(self): 13 print('C') 14 pass 15 16 class D(B): 17 # def test(self): 18 # print('D') 19 pass 20 21 class E(C): 22 # def test(self): 23 # print('E') 24 pass 25 26 class F(D,E): 27 # def test(self): 28 # print('F') 29 pass 30 f1=F() 31 f1.test() #经典类：F->D->B->A-->E--> 32 33 print(F.__mro__) 34 35 #F-->D->B-->E--->C--->A新式类
9.在子类中调用父类的方法
1 class Vehicle: 2 Country='China' 3 def __init__(self,name,speed,load,power): 4 self.name=name 5 self.speed=speed 6 self.load=load 7 self.power=power 8 def run(self): 9 print('开动啦') 10 print('开动啦') 11 class Subway(Vehicle): 12 def __init__(self,name,speed,load,power,line): 13 Vehicle.__init__(self,name,speed,load,power) 14 self.line=line 15 16 def show_info(self): 17 print(self.name,self.speed,self.load,self.power,self.line) 18 19 def run(self): 20 Vehicle.run(self) 21 print('%s %s 线，开动啦' %(self.name,self.line)) 22 line13=Subway('北京地铁','10km/s',1000000000,'电',13) 23 24 line13.show_info() 25 26 line13.run()
10.super方法的使用
1 class Vehicle1: 2 Country='China' 3 def __init__(self,name,speed,load,power): 4 self.name=name 5 self.speed=speed 6 self.load=load 7 self.power=power 8 def run(self): 9 print('开动啦') 10 print('开动啦') 11 class Subway(Vehicle1): 12 def __init__(self,name,speed,load,power,line): 13 # Vehicle.__init__(self,name,speed,load,power) 14 # super().__init__(name,speed,load,power) #super(__class__,self).__init__(name,speed,load,power) 15 super(Subway,self).__init__(name,speed,load,power) 16 self.line=line 17 def show_info(self): 18 print(self.name,self.speed,self.load,self.power,self.line) 19 def run(self): 20 # Vehicle.run(self) 21 super().run() 22 print('%s %s 线，开动啦' %(self.name,self.line)) 23 line13=Subway('北京地铁','10km/s',1000000000,'电',13) 24 line13.show_info() 25 line13.run() 26 27 print(line13.__class__)
