本学期我参加了一个网络编程课，我的项目包含一个测验游戏，带有简单的图形界面。
我想显示问题，就像玩家点击按钮回答一样。
问题是，我不知道如何在"wait for click"中对python进行编码，代码正在执行直到结束。
我尝试使用boolean条件的一段时间（如果没有点击然后等待），这就像我想要的那样等待，但是没有显示图形界面......
这是我的代码，我有点绝望
感谢您的帮助。

答案 0 :(得分：1)
如果您希望程序等待按钮单击，那么您应该在按钮回调命令中执行下一个要执行的代码。我将问题代码转移到名为nextQuestion的方法中，该方法在条件满足后在checkAnswer中调用。我还做了一些小的改进，有足够的评论来解释它们（我认为）。
以下是完整的代码：
