我在程序中一直遇到这个错误，我不知道如何修复它，因为我是python 3中的初学者。每当我尝试在菜单中更改网格的大小时就会出现错误。然后我去运行宝藏网格，我得到这个错误，并不知道如何解决。任何和所有的帮助表示赞赏！
错误：
Exception in Tkinter callback

答案 0 :(得分：3)
只处理该特定问题，您将int()与tk.Entry()进行比较，即。 len(treasureChests) < treasure_amount len返回int，treasure_amount是条目框。要仅解决该问题，请将while循环更改为：
while len(treasureChests) < int(treasure_amount.get()):
使用.get()，它会检索输入框的值，并int()从默认str转换
可能会出现更多问题。
作为旁注，请尝试使用较少的global语句。
编辑进一步检查，我发现这是一个常见的名称错误，你有两个不同的对象设置为同一个变量。第一个是在顶部：
treasure_amount = 10
另一个在你的settings_window中：
global treasure_amount
treasure_amount = tk.Entry(settings, width=50, fg="magenta")
所以你应该改变其中一个的名字。
