Python-AttributeError:type object'；MyClass'；没有属性'；名称'；

我有3个python文件

MyModule.py

class MyClass:
    def __init__(self, name):
        self.name = name

    @classmethod
    def hello(self):
        print('Hello ' + self.name)

import pickle
from MyModule import *

me = pickle.load(file('my_pkl.pickle','rb'))
me.hello()

import pickle
from MyModule import *

me = MyClass('Anil')
pickle.dump(me, open('my_pkl.pickle','wb'))

Loader.py

class MyClass:
    def __init__(self, name):
        self.name = name

    @classmethod
    def hello(self):
        print('Hello ' + self.name)

import pickle
from MyModule import *

me = pickle.load(file('my_pkl.pickle','rb'))
me.hello()

import pickle
from MyModule import *

me = MyClass('Anil')
pickle.dump(me, open('my_pkl.pickle','wb'))

Dumper.py

class MyClass:
    def __init__(self, name):
        self.name = name

    @classmethod
    def hello(self):
        print('Hello ' + self.name)

import pickle
from MyModule import *

me = pickle.load(file('my_pkl.pickle','rb'))
me.hello()

import pickle
from MyModule import *

me = MyClass('Anil')
pickle.dump(me, open('my_pkl.pickle','wb'))

当我超过Loader.py时，我得到以下错误：

AttributeError: type object 'MyClass' has no attribute 'name'

如何访问名称实例vaiable？

您正在使用实例方法作为类方法。让它成为一个实例方法

# remove @classmethod decorator
# called on instance: me.hello()

def hello(self):
    print('Hello ' + self.name)

为什么

me.hello（）

？@thinkerou我只想在

me

实例上调用

hello（）

方法，但是

me

和class

MyClass

并不重要。请阅读和了解

@staticmethod

和

@classmethod

。
