Question

目录结构是：

ga/ :

    PP.py

    this.py

    that.py

tripathi/:

    nn.py # contains function net

    neuron.py #contains function node

    aicc.py # contains function AICC

    blah.py

    variable.py

    __init__.py

我正在尝试使用＆＃39; tripathi＆＃39;目录作为模块。因此，__init__.py

#__init__.py 

from nn import net

from neuron import node

from aicc import AICC

#variable.py

def initialise (): #to initialise global variables


    global globe1, globe2, globe3

    globe1 = 8

    globe2 = [1,2,3,4,5]

    globe3 = "bakar"

文件variable.py包含一些要在this.py，that.py和PP.py

中使用的全局变量

#this.py

from tripathi import node 

from tripathi import AICC #function AICC in aicc.py

from tripathi import variables #file variables.py

variables.initialise() #all global variables initialised

this_one = variables.globe1

现在，that.py有

#that.py

import this

AttributeError : 'module' object has no attribute 'globe1'

为什么会出错？ import this语句（在that.py中）是否导入this.py中导入的所有模块？

编辑：我正在使用IPython笔记本。

Answer 1

使用global关键字是不够的。您必须在模块级别声明变量：

#variable.py

globe1 = 8
globe2 = [1,2,3,4,5]
globe3 = "bakar"

def initialise():
    pass # nothing to do there anymore.

AttributeError：＆＃39;模块＆＃39;对象没有属性＆＃39; globe1＆＃39;
