* 我相信lvl1[(x,y)] = getattr(__import__('mapTiles'), tile_name)(x, y)导致了问题，我将其更改为具有相同问题的直接导入，这里的循环导入是......mapTiles导入世界，在load_tiles()函数中，它导入mapTiles。我不知道如何重组它以阻止圈子，有什么想法吗？*我正在制作一个文本RPG游戏，我编码了所有瓷砖并能够与之交互，但是当我去运行游戏时，它给了我下面的错误。我在任何地方都看不到循环导入，所以我不明白发生了什么。(如果您需要任何其他代码，请告诉我(

我修复了它，错误是从getattr导入的。我合并了这两个文件，添加了一个 try/except 来捕获索引错误，并添加了一堆条件，这些条件在任何坐标处实例化磁贴名称。
