Python classmethod 修饰符实例讲解

代码部分：

class Dog( ):
    name="huazi"
    def __init__(self,name):
        self.name=name

    @classmethod
    def eat(self):
        print("%s is eating %s"%(self.name,"a"))
    def talk(self):
        print("%s is talking"%self.name)
d=Dog("erha")
d.eat()

d.talk()

执行结果：
huazi is eating a
erha is talking

结论：@classmethod下的类方法eat（）只能调用类变量name
