python静态方法怎么使用self

@staticmethod  # 静态方法

@classmethod  # 类方法

@property   # 属性方法

class Dog(object):

    def __init__(self, name):

        self.name = name

    @staticmethod

    def eat():

        print(" is eating ")

# 类调用

Dog.eat()

# 对象调用

d = Dog('dog1')

d.eat()

class Dog(object):

    food2 = "food2"

    def __init__(self, name):

        self.name = name

    @classmethod

    def eat(self):

        print(" is eating %s " %self.food2)

Dog.eat()

d = Dog('dog1')

d.eat()

或者这样：

class Dog(object):

    food2 = "food2"

    def __init__(self, name):

        self.name = name

    @classmethod

    def eat(cls):

        print(" is eating %s " %cls.food2)

Dog.eat()

d = Dog('dog1')

d.eat()

class Dog(object):

    def __init__(self, name):

        self.name = name    @property

    def eat(self):

       # print("I am eating")

        return 'eat'

    def abc(self):

        print('abc')d = Dog('xg')print (d.eat)
