现在尝试让它工作一段时间但是，我想要做的就是当用户输入选择时打开GUI＃5;＆＃39;但我不确定是否有一种不同的方式来打电话给某个班级或者其他什么东西，在网上找了一下看不出任何有用的例子来帮助你。任何帮助都会非常感激，欢呼。
答案 0 :(得分：0)
此时我无法运行代码，但我发现了一个错误。
创建dashboard时，它需要父实例 - 例如root - 但在menu()中，您使用Frame这是类名，而不是实例。
在menu()中，您必须在创建root之前创建dashboard，然后再使用root.mainloop()。
elif choice == "5":
print("Dashboard")
root = Tk()
root.title("Dashboard")
root.geometry("300x170")
app = dashboard(root)
root.mainloop()
编辑：完整的工作代码。
因为现在root是main()内的局部变量，所以dashboard我使用self.master代替root - 请参阅command=self.master.destroy
