有一个美好的早晨，
我正在和一位讲师一起准备机器人 Karl 的世界，以便在大学教授 Python，这不仅是熟悉的记忆。
世界已经准备就绪，应用程序使用了 TKInter 库。我有一个问题要问更有经验的 Python 专家，当我尝试在命令行中运行它时，我看到两个空的 TKInter 窗口，并显示消息“抛出异常！给定的机器人世界已经被删除”。在 IDLE 中也是如此。
由于该项目也可用于图像，因此我在这里使用存储库服务 uschovna.cz - Karel Robot保存了它。
我承认我对 TKInter 还不是很友好，但它已经被选中用于教学，所以我可能只需要在 robotswindow.py 类中添加一两个方法，一切都会正常运行。
以下是错误消息列表：
Starting with command line:
>>> from robot import *
===== Module robot.color ===== START
===== Module robot.color ===== STOP
===== Module robot.dir4 ===== START
===== Module robot.dir4 ===== STOP
===== Module robot.robotworld ===== START
===== Module robot.robotworld ===== STOP
===== Module robot.robotwindow ===== START
=== ROBOTS_ICON_DIRECTORY = '/home/wanbli/robot/IMGR/'
===== Module robot.robotwindow ===== STOP
>>> rwd = new_empty_world(3, 3)
>>> rww = create_window_for(rwd)
I see two empty TK windows and message "Exception thrown! The given robot has already been removed.".

你知道如何解决这个问题吗？
