静态方法,类方法,属性方法,属性方法实例-创新互联

#静态方法用的少,相当于类的工具包,访问不了类或实例中的任何属性
classDog(object):
   def__init__(self,name):
       self.name=name


   @staticmethod#实际上跟类没关系了,就只是一个函数了,名义上归类管
   defeat(self):
       print("%s is eating %s"%(self.name,'dd'))

   deftalk(self):
       print("%s is talking"%self.name)
d=Dog("chenronghua")
d.eat(d) #把自己传到eat函数,使self有效
d.talk()
