Python :模块'xxx‘没有属性'xxx’

Question

我是Python新手，我正在从事一个个人项目，以获得更舒适的问题解决和规划的事情。我试图在另一个模块中引用一个变量，但我似乎无法让它正常工作，这让我发疯了。我已经做了一些类似的话题，但恐怕我还没有足够的知识来阅读解决方案，并找出如何将它们应用到我的项目中。以下是“phaseOne.py”的代码：

import difficultySelection
difficultySelection.diffSel()
print(f'   {difficultySelection.difficulty1}   ')

以下是“difficultySelection”的代码：

def diffSel(mode_selected = False):
     while mode_selected == False:
          print('Select difficulty (normal/hard)')
          mode_input = input()
          if mode_input == "normal":
               mode_selected = True
               difficulty1, difficulty2, difficulty3, difficulty4 = 1,2,3,4
               return mode_selected, difficulty1, difficulty2, difficulty3, difficulty4
          elif mode_input == "hard":
               mode_selected = True
               difficulty1, difficulty2, difficulty3, difficulty4 = 2,4,6,8
               return mode_selected, difficulty1, difficulty2, difficulty3, difficulty4
          else:
               print("Input not accepted, please enter 'normal' or 'hard'")

通过这个设置，我一直收到错误"AttributeError:模块'difficultySelection‘没有属性'difficulty1'“，其中调用了"difficultySelection.difficulty1”。

Answer 1

弄明白了！结果，我没有正确地引用另一个模块中的变量。我将引用从"difficultySelection.difficulty1“转换为"difficultySelection.diffSel().difficulty1”，这似乎解决了一些问题。可能会产生新的问题，但这只是另一个挑战！
