如何在Windows中的python3中导入文件/模块？

我的程序需要利用2个文件作为来源。这适用于linux，但不适用于Windows：

然后，我将它们导入如下：

import random
from hangman_art import stages, logo
from hangman_words import word_list

print(logo)

出现错误：

File "c:\Users\MANNY\Documents\python100\hangman\hangman_game.py", line 2, in <module>
    from hangman_art import stages, logo
ImportError: cannot import name 'stages' from 'hangman_art'

hangman_art.py的代码：

stages = ['''
  +---+
  |   |
  O   |
 /|\  |
 / \  |
      |
=========
''', '''
