 6 # 类的方法
 7 class Animal:
 8     def __init__(self,name):
 9         self.name = name
10         self.num = None
11     count = 10
12     hobbie = "wohaoshuai"
13
14     @classmethod #将下面方法变成只能通过类方式去调用而不能通过实例方式去调用。因此调用方法为：Animal.talk(). ！！！！类方法，不能调用实例变量
15     def talk(self):
16         print("{0} is talking...".format(self.hobbie))#因为hobbie为类变量所以可以通过类方式或者实例方式，若括号中为self.name实例变量则只能通过Animal.talk()方式调用
17
18     @staticmethod #当加上静态方法后，此方法中就无法访问实例变量和类变量了,相当于把类当作工具箱，和类没有太大关系
19     def walk():
20         print("%s is walking...")
21
22     @property #属性，当加了property后habit就变成一个属性了就不再是一个方法了,调用时不用再加()
23     def habit(self): #习惯
24         print("%s habit is xxoo" %(self.name))
