@staticmethod
classDog(object):
def__init__(self, name):
self.name = name
@staticmethod
defeat(self):
print('eatttt,,,,,%s'%self.name)
d = Dog('f')
# d.eat
Dog.eat(d)
静态方法，只是名义上归类管理，实际上在静态方法里访问不了类或者实例的任何属性。
@classmethod
classDog(object):
name ='vv'
def__init__(self, name):
self.name = name
# @staticmethod
@classmethod
defeat(self):
print('eatttt,,,,,%s'%self.name)
d = Dog('f')
d.eat()
类方法只能访问类变量，不能访问实例变量
@property
classDog(object):
def__init__(self, name):
self.name = name
# @staticmethod
# @classmethod
@property
defeat(self):
print('eatttt,,,,,%s'%self.name)
d = Dog('f')
d.eat
属性方法，把一个方法变成属性,不能直接删除该属性（如del d.eat，不可以），可以定义一个@eat.deleter,在这个方法里删除一些这个属性用到的一些私有属性
classDog(object):
def__init__(self, name):
self.name = name
self.__food ='defaultfood'
# @staticmethod
# @classmethod
@property
defeat(self):
print('eatttt,,,,,%s,,,%s'%(self.name,self.__food))
@eat.setter
defeat(self,food):
# print('set to food:', food)
self.__food ='baozi'
@eat.deleter
defeat(self):
delself.__food
print('删除')
d = Dog('f')
d.eat
d.eat ='包子'
d.eat
del d.eat
