如何解决Tkinter不允许我在画布上放置条目
当我自己运行此代码时，它什么也不做。但是当与第二组一起运行时，会产生一个非常奇怪的错误。它旨在创建一个窗口，要求输入一个条目，然后放置一个确认按钮，但该条目不会放置并产生错误。如果删除该条目，该错误消失，但是我需要该条目。
我已经搜索了堆栈溢出问题，却找不到任何解决问题的方法。
如果您对我有改善问题的建议，请在评论中注明！

它应该会出现一个窗口，询问您要打几轮，但不会。
解决方法
我不知道您在代码中做了什么（我看了一下，但是太复杂了），如果您的问题是创建更多的窗口，请看一下我对此发表的这篇文章：how to make more windows with tkinter
