```通过继承创建的新类称为“子类”或“派生类”。被继承的类称为“基类”、“父类”或“超类”。继承概念的实现方式主要有2类：实现继承、接口继承。1、实现继承是指使用基类的属性和方法而无需额外编码的能力；2、接口继承是指仅使用属性和方法的名称、但是子类必须提供实现的能力(子类重构爹类方法)；## 最简单的继承class person(object): def talk(self): print('talk english....')class ypeople(person): # def talk(self): #要是没有重新定义talk会调用父类里的talk print("talk chinese") def walk(self): print("yperson is runing....")b=ypeople()b.talk()b.walk()## 先继承再重构class person(object): 父类 def __init__(self,name,age): self.name=name self.age=age self.sex="normal" def talk(self): print('talk english....')class bperson(object): passclass ypeople(person): def __init__(self,name,age,strength): #先继承，再重构 person.__init__(self,name,age) self.www="www" print(self.name,self.age,self.sex) def talk(self): #要是没有重新定义talk会调用父类里的talk person.talk(self) #继承方法（一般不这么做，重复执行） print("talk chinese") def walk(self): print("yperson is working...")b=ypeople("王东",30,"strong")b.talk()b.walk()## 类的继承运用例子class School(object): """"学校成员基类""" number=0 def __init__(self,name,age,sex): self.name=name self.age=age self.sex=sex self.enroll() #在基类里内部调用（相当于子类默认调用） def enroll(self): """注册""" print("%s欢迎加入我们学院！"%self.name) School.number+=1 #把值赋给公有属性(变成全局的)直接self.number只是在实例里面创建了一个变量number=0然后加1 def tell(self): """打印自己的信息""" print("------info:%s-------"%self.name) for k,v in self.__dict__.items(): print("\t",k,v) print("------end-------" ) def __del__(self): # 析构 print("[%s] 被开除了！"%self.name) School.number-=1class newschool(object): def openschool(self,addr): print("open in the %s"%addr)class Teacher(School,newschool): # 多继承（继承多个类） """讲师类""" def __init__(self,name,age,sex,salary,course): #School.__init__(self,name,age,sex) #经典类 super(Teacher,self).__init__(name,age,sex) # 新式类 self.salary=salary self.coures=course def teaching(self): print("Teacher [%s] is teaching [%s]"%(self.name,self.coures))class Student(School): """学生类""" def __init__(self,name,age,sex,course,fee): School.__init__(self,name,sex,age) self.course=course self.fee=fee self.amount=0 def pay_fee(self,amount): print("student [%s] has just paid [%s]"%(self.name,self.amount)) self.amount+=amountt1=Teacher("王肖",29,'F*M',20000,"Python")s1=Student("王鼎",26,"N/A",'Python',30000)s2=Student("苏晓",22,"F","Python",5000)print(School.number) #输出总共创建次数print(t1.number) #输出t1实例本身创建次数print(School.number) #输出总共创建次数del s1 #删除s1print(School.number) #输出总共创建次数a=s1.__dict__ #把信息转换成列表print(a)t1.tell()t1.openschool("上海") #多继承测试
