day25-python之继承组合

1.上节回顾

 class School:
     x=1
     def __init__(self,name,addr,type):
         self.Name=name
         self.Addr=addr
         self.Type=type

     def tell_info(self):
         print('学校的详细信息是：name:%s addr:%s' %(self.Name,self.Addr))

 # s1=School('oldboy','沙河','私立')

 # print(s1.__dict__)
 #
 # print(School.__dict__)
 #
 # s1.tell_info()
 # School.tell_info(s1)

2.静态属性

 class Room:
     tag=1
     def __init__(self,name,owner,width,length,heigh):
         self.name=name
         self.owner=owner
         self.width=width
         self.length=length
         self.heigh=heigh

     @property
     def cal_area(self):
         # print('%s 住的 %s 总面积是%s' % (self.owner,self.name, self.width * self.length))
         return  self.width * self.length
     @property
     def cal1_area(self):
         return self.width * self.length

     def test(self):
         print('from test',self.name)

     @classmethod
     def tell_info(cls,x):
         print(cls)
         print('--》',cls.tag,x)#print('--》',Room.tag)
     # def tell_info(self):
     #     print('---->',self.tag)
     @classmethod
     def tell_info1(cls,x):
         print(cls)
         print('-->>',cls.tag,x)

 # print(Room.tag)

 # Room.test(1) #1.name
 # r1=Room('厕所','alex',100,100,100000)
 # Room.tell_info(10)

 r1=Room('厕所','alex',100,100,100000)
 r2=Room('公共厕所','yuanhao',1,1,1)
 # print('%s 住的 %s 总面积是%s' %(r1.owner,r1.name,r1.width*r1.length))
 # print('%s 住的 %s 总面积是%s' %(r2.owner,r2.name,r2.width*r2.length))
 # r1.cal_area()
 # r2.cal_area()
 print(r1.cal_area)
 print(r2.cal_area)
 print(r1.name)
 print(r2.name)

3.类方法

 class Room:
     tag=1
     def __init__(self,name,owner,width,length,heigh):
         self.name=name
         self.owner=owner
         self.width=width
         self.length=length
         self.heigh=heigh

     @property
     def cal_area(self):
         # print('%s 住的 %s 总面积是%s' % (self.owner,self.name, self.width * self.length))
         return  self.width * self.length
     @property
     def cal_area1(self):
         return self.width * self.length

     def test(self):
         print('from test',self.name)

     @classmethod
     def tell_info(cls,x):
         print(cls)
         print('--》',cls.tag,x)#print('--》',Room.tag)
     # def tell_info(self):
     #     print('---->',self.tag)

     @classmethod
     def tell_info1(cls,x):
         print(cls)
         print('-->>',cls.tag,x)

 # print(Room.tag)

 # Room.test(1) #1.name
 r1=Room('厕所','alex',100,100,100000)
 # Room.test(r1)
 Room.tell_info(10)

4.静态方法

 class Room:
     tag=1
     def __init__(self,name,owner,width,length,heigh):
         self.name=name
         self.owner=owner
         self.width=width
         self.length=length
         self.heigh=heigh

     @property
     def cal_area(self):
         # print('%s 住的 %s 总面积是%s' % (self.owner,self.name, self.width * self.length))
         return  self.width * self.length

     @classmethod
     def tell_info(cls,x):
         print(cls)
         print('--》',cls.tag,x)#print('--》',Room.tag)
     # def tell_info(self):

     @staticmethod
     def wash_body(a,b,c):
         print('%s %s %s正在洗澡' %(a,b,c))

     @staticmethod
     def wash_body1(a,b,c):
         print('%s %s %s正在洗澡'%(a,b,c))

     def test(x,y):
         print(x,y)

 # Room.wash_body('alex','yuanhao','wupeiqi')

 # print(Room.__dict__)

 r1=Room('厕所','alex',100,100,100000)
 #
 # print(r1.__dict__)
 # r1.wash_body('alex','yuanhao','wupeiqi')

 # Room.test(1,2)
 r1.test(1)

5.组合

 # class Hand:
 #     pass
 #
 # class Foot:
 #     pass
 #
 # class Trunk:
 #     pass
 #
 # class Head:
 #     pass

 # class Person:
 #     def __init__(self,id_num,name):
 #         self.id_num=id_num
 #         self.name=name
 #         self.hand=Hand()
 #         self.foot=Foot()
 #         self.trunk=Trunk()

 #
 #
 # print(p1.__dict__)

 # class School:
 #     def __init__(self,name,addr):
 #         self.name=name
 #         self.addr=addr
 #
 #     def zhao_sheng(self):
 #         print('%s 正在招生' %self.name)
 #
 # class Course:
 #     def __init__(self,name,price,period,school):
 #         self.name=name
 #         self.price=price
 #         self.period=period
 #         self.school=school
 # #
 # #
 # #
 # s1=School('oldboy','北京')
 # s2=School('oldboy','南京')
 # s3=School('oldboy','东京')
 #
 # # c1=Course('linux',10,'1h','oldboy 北京')
 # c1=Course('linux',10,'1h',s1)
 # #
 # print(c1.__dict__)
 # print(c1.school.name)
 # print(s1)

 class School:
     def __init__(self,name,addr):
         self.name=name
         self.addr=addr

     def zhao_sheng(self):
         print('%s 正在招生' %self.name)

 class Course:
     def __init__(self,name,price,period,school):
         self.name=name
         self.price=price
         self.period=period
         self.school = school

 s1=School('oldboy','北京')
 s2=School('oldboy','南京')
 s3=School('oldboy','东京')
 #
 # c1=Course('linux',10,'1h','oldboy 北京')
 c1=Course('linux',10,'1h',s1)

 msg='''
 1 老男孩 北京校区
 2 老男孩 南京校区
 3 老男孩 东京校区
 '''
 while True:
     print(msg)
     menu={
         '':s1,
         '':s2,
         '':s3
     }
     choice=input('选择学校>>: ')
     school_obj=menu[choice]
     name=input('课程名>>： ')
     price=input('课程费用>>： ')

     new_course=Course(name,price,period,school_obj)
     print('课程【%s】属于【%s】学校' %(new_course.name,new_course.school.name))

6.继承

 class Dad:
     '这个是爸爸类'
     money=10
     def __init__(self,name):
         print('爸爸')
         self.name=name
     def hit_son(self):
         print('%s 正在打儿子' %self.name)

 class Son(Dad):
     money = 1000000000009
     def __init__(self,name,age):
         self.name=name
         self.age=age

     def hit_son(self):
         print('来自儿子类')
 # print(Son.money)
 # Son.hit_son(Son('andy',12))
 # print(Dad.__dict__)
 # print(Son.__dict__)
 s1=Son('alex',18)
 # s1.hit_son()
 print(s1.money)
 print(Dad.money)
 print(s1.name)
 print(s1.money)
 print(s1.__dict__)
 s1.hit_son()

7.接口继承

 import abc
 class All_file(metaclass=abc.ABCMeta):
     @abc.abstractmethod
     def read(self):
         pass

     @abc.abstractclassmethod
     def read1(self):
         pass

     @abc.abstractmethod
     def write(self):
         pass

     @abc.abstractclassmethod
     def write1(self):
         pass

 class Disk(All_file):
     def read(self):
         print('disk read')

     def write(self):
         print('disk write')

 class Cdrom(All_file):
     def read(self):
         print('cdrom read')

     def write(self):
         print('cdrom write')

 class Mem(All_file):
     def read(self):
         print('mem read')

     def write(self):
         print('mem write')

 class Mem1(All_file):
     def read(self):
         print('mem read')

     def write(self):
         print('mem write')
 #
 m1=Mem1()
 m1.read()
 m1.write()

8.继承顺序

 #coding:utf-8
 class A:
     def test(self):
         print('A')
     pass
 class B(A):
     # def test(self):
     #     print('B')

     pass
 class C(A):
     def test(self):
         print('C')
     pass

 class D(B):
     # def test(self):
     #     print('D')
     pass

 class E(C):
     # def test(self):
     #     print('E')
     pass

 class F(D,E):
     # def test(self):
     #     print('F')
     pass
 f1=F()
 f1.test()   #经典类：F->D->B->A-->E-->

 print(F.__mro__)

 #F-->D->B-->E--->C--->A新式类

9.在子类中调用父类的方法

 class Vehicle:
     Country='China'
     def __init__(self,name,speed,load,power):
         self.name=name
         self.speed=speed
         self.load=load
         self.power=power
     def run(self):
         print('开动啦')
         print('开动啦')
 class Subway(Vehicle):
         def __init__(self,name,speed,load,power,line):
            Vehicle.__init__(self,name,speed,load,power)
            self.line=line

         def show_info(self):
             print(self.name,self.speed,self.load,self.power,self.line)

         def run(self):
             Vehicle.run(self)
             print('%s %s 线，开动啦' %(self.name,self.line))
 line13=Subway('北京地铁','10km/s',1000000000,'电',13)

 line13.show_info()

 line13.run()

10.super方法的使用

 class Vehicle1:
     Country='China'
     def __init__(self,name,speed,load,power):
         self.name=name
         self.speed=speed
         self.load=load
         self.power=power
     def run(self):
         print('开动啦')
         print('开动啦')
 class Subway(Vehicle1):
         def __init__(self,name,speed,load,power,line):
            # Vehicle.__init__(self,name,speed,load,power)
            # super().__init__(name,speed,load,power)  #super(__class__,self).__init__(name,speed,load,power)
            super(Subway,self).__init__(name,speed,load,power)
            self.line=line
         def show_info(self):
             print(self.name,self.speed,self.load,self.power,self.line)
         def run(self):
             # Vehicle.run(self)
             super().run()
             print('%s %s 线，开动啦' %(self.name,self.line))
 line13=Subway('北京地铁','10km/s',1000000000,'电',13)
 line13.show_info()
 line13.run()

 print(line13.__class__)
