Python 3.x 制作二维贴图['；非类型'；对象不可编辑]

只是想让图像显示在二维数组中。我试图完成的是我在字典中写的每一件事，都会取代我在另一个.txt文件中写的东西

我真的不想发布400行代码。所以我删除了很多代码，只是为了解决同样的问题

def readFile（文件名）： 我试图通过返回char_位置来了解问题所在。特金特出现了。但只有一张照片来了。没有别的了。当我写pass而不是return时，我得到了这个消息

第93行，在createObjects中 对于游戏地图中的i：

TypeError:“非类型”对象不可编辑

print("Define PICTURES before you can start")

• readFile

  不返回任何内容
• 所以

  游戏地图

  （第54行）将是

  无

• 因此，在

  createObjects

  （第84行）中，游戏地图中i的

  （第93行）将尝试迭代无

• 因此引发

  TypeError:“NoneType”对象不可编辑

您知道如何解决这个问题吗？我已经试了几个小时，但没有成功。现在的问题是，它只显示我的黑屏。而不是二维数组。这是一张照片。那是另一个问题。打开一个新的问题，试着解释一下你到目前为止尝试了什么。
