类的继承代码

#Author Kangclass Person(object): #父类 countPerson = 0 #公有属性 def __init__(self,name,sex): #类的初始化 self.Name = name self.Sex = sex Person.countPerson += 1 #统计注册人数,必须要这样写，否则无法形成统计 def walking(self): #类的方法 print("%s is walking"%self.Name)class BlackPerson(Person): #子类 def __init__(self,name,sex,language): #初始化函数，先继续父类，再重构自己 Person.__init__(self,name,sex) self.Language = language def talking(self): #子类的方法 print("%s is talking,Lanaguage is %s"%(self.Name,self.Language)) def walking(self): #重构父类的方法 print("我是重构了父类的方法，walking.......！！！！！")b2 = BlackPerson("kang","F","chiness")b1 = BlackPerson("Jack","F","English")b1.talking()b1.walking()print("当前人数:",Person.countPerson)

结果：Jack is talking,Lanaguage is English我是重构了父类的方法，walking.......！！！！！当前人数: 2
