嗨我的代码有问题，在onbutton方法中，n取数字100或更少作为参数，它工作正常。但是当数字超过100时，我的计算机会冻结，最后它会崩溃。我需要简化我的代码并希望以任何方式使其工作。有什么建议？我知道在我的代码中有一些sql选择，但是没有注意到只是把它们想象为数字和文本在第一次选择它给出了我想要创建的静态文本的数量，在第二次选择它需要内容与我的内容想填补。

看起来您正在循环结果集并设置各种标签。但是，您似乎还在每次迭代时覆盖标签。我不确定你为什么要那样做。
我对你的问题的猜测是查询变得太大了。尝试在没有wx的普通Python中进行查询，看看执行需要多长时间。如果你可以测量它花了多长时间，那么在那段时间里，它会阻止wxPython的主循环，这就是它冻结的原因。要解决这个问题，您需要将查询放入一个单独的线程中，并将结果发送回wxPython以更新显示。
