root.after方法冻结了我的窗口（Tkinter Python 3）

Question

我正在为一个任务在学校编写一个Hangman GUI。我是编程新手，所以我没有很多模块的知识，所以我的代码可能会不必要的长。我在窗口底部放置了一个状态栏，告知用户他们的猜测是否过长或已经猜到了。 2秒后，文本应恢复为"Everything's fine :)"，但该窗口在2秒内变为无响应，并且标签不会通知用户无效的猜测。
注意：我是编程新手，所以请尽量使用您的解释。
非常感谢！
的问题是在过去的功能

下面是代码：

root.mainloop() 

Answer 1

的root.after调用一个需要调用的函数作为它的参数，从而使statusBar.config事件被称为在2秒内，而不是立即。如果你这样做，它会使GUI响应。

root.after(2000, lambda: statusBar.config(text="Everything's fine :)"))
