python 类继承

class CAnimal:    def __init__(self,param):        print("CAnimal init method called.")        self.name = param    #property 定义一个属性name    @property    def name(self):        return self.__name    #为属性 name 定义修改器    @name.setter    def name(self,name):        self.__name = name    def show(self):        print(self.name,"is an animal")    def __del__(self):        print("CAnimal del method called")class CDog(CAnimal):    def __init__(self,name,year):        CAnimal.__init__(self,name)        self.year = year        print("CDog init method called")    @property    def year(self,data):        self.__year= data    def show(self):        print(self.name,self.year,"is an dog")    def __del__(self):        print("CDog del method called.")dog =CDog("habagou",5)dog.show()

结果：

CAnimal init method called.
CDog init method called
('habagou', 5, 'is an dog')
CDog del method called.
