python中的两个窗口，吓到我了

Question

** 没关系！ ** 这个问题已经回答了！它只需要在底部而不是根蜂蜡......

是的。这是底部。它只需要一点代码清理:)....没关系。还是谢谢！

#omit root
app = App()
app.mainloop()

我已经努力了两个小时来摆脱第二个窗口。在我实现了询问文件夹名称的弹出窗口后，程序运行时我突然打开了两个窗口。我只想要一个，真的很烦人。我希望这个程序用四个按钮打开一个窗口，并在它们上方有一个标题。其中一个按钮要求输入，然后它就消失了。有人可以帮我回到一个窗口吗？谢谢你。我为乱七八糟的代码道歉，这是我的第一个这种风格的脚本。

在您的app 类中，您已经定义了一个Tk。因此，当您定义一个app 和另一个Tk 时，您将创建两个窗口。删除一个或另一个应该只创建一个窗口。
