当我使用CMD运行Python Tkinter窗口时，它不会打开

如果我在空闲状态下运行代码，它可以正常工作，但是当我尝试使用CMD或pyinstaller执行它时，它不会创建窗口。我不确定这是否是因为我遗漏了什么，我也研究了其他问题，但似乎没有任何帮助

我的自定义模块只提供数据并生成主窗口

它打印所有内容，但不生成窗口。我想不出是怎么回事，如果能帮上忙，我将不胜感激

它没有给出错误消息

如果您需要我的其他模块的任何数据，请告诉我

如果是因为

mainloop

我将

mainloop

函数放在哪里

您缺少

mainloop（）

函数。它应该放在GUI创建的末尾。

我应该把它放在哪里mainloop@Connor它应该放在GUI语句的末尾——假设您正在创建主屏幕，它应该放在那里。如果你给我一些时间，我会仔细阅读整个代码，并试图找到它应该放在哪里，但我更希望你能深入了解它如果我使用的是toplevel，我需要为每个代码执行mainloop吗toplevel@Connor不可以。在每个Tkinter应用程序中，应该正好有一个

mainloop（）

函数的调用。好的，谢谢。您是否也可以帮助我执行此

无法调用“event”命令：应用程序在执行从“ttk:：ThemeChanged”中调用的“event generate$w”（过程“ttk:：ThemeChanged”第6行）时已被销毁
请将此代码缩减为一个完整的代码。例如，如果窗口出现问题，我们不需要任何数据库代码，而且可能只需要一个按钮而不是一打按钮。
