如何将python脚本添加到GUI？

我在向GUI添加脚本时遇到问题。Python脚本（运行爬网和比较刮取的日期）和GUI工作良好。我不知道该怎么做，我只是将代码复制到“def run”中，但随后出现错误：“valueerror:signal仅在主线程中工作”。有人能解释一下我怎么做吗？谢谢

您有一个格式问题，看起来

class

之前的第一位缩进了一段额外的时间。你能把它改成实际代码的样子吗？如果你的脚本需要很长时间才能运行，那么你应该把它放到线程中或者从线程调用它。任何一种方法都应该有效。你能发布一个你的爬虫的小例子，让我们看看它的功能吗？我怀疑这是引发错误的原因，因为您提到的异常似乎与wxPythonAt无关。在开始脚本中，运行两个爬行器：process=CrawlerProcess（get_project_settings（））process.crawl（'test'，domain='..com'）process.crawl（'pin'，domain='..com'）process start（）爬行器以csv格式保存数据，然后，我的脚本打开csv文件并比较日期。GUI脚本甚至不能与前一条评论中附加的代码一起工作。@whrrgarbl我编辑了代码，这是写文章的错误。
