1、class Animal(object): result = 1 #首先创建一个类，然后我们定义一下类属性。
2、class Animal(object): result = 1 def __init__(self, name): self.name = name #然后我们进行初始化，设置实例的属性。
3、class Animal(object): result = 1 def __init__(self, name): self.name = name @staticmethod def welcome(): print("welcome to the Zoo!") #然后我们就可以设置一下静态方法了，静态方法不调用实例属性和类属性。
4、class Animal(object): result = 1 def __init__(self, name): self.name = name @staticmethod def welcome(): print("welcome to the Zoo!") @classmethod def total(cls): print("the total animal is %d." % cls.result) #创建类方法就可以调用类属性。
5、class Animal(object): result = 1 def __init__(self, name): self.name = name @staticmethod def welcome(): print("welcome to the Zoo!") @classmethod def total(cls): print("the total animal is %d." % cls.result) def play(self): print("playing with %s." % self.name) #最后就是创建实例方法，调用实例的属性。
6、class Animal(object): result = 1 def __init__(self, name): self.name = name @staticmethod def welcome(): print("welcome to the Zoo!") @classmethod def total(cls): print("the total animal is %d." % cls.result) def play(self): print("playing with %s." % self.name)Animal.welcome()Animal.total()lion = Animal("Lion")lion.play()#这个时候就能同时运用三种方法了。
