command-line - 遍历所有可用新闻文章后的回溯

Question

我正在制作一个 python CLI 实用程序，它将回答诸如“15 + 15”或“字母表中有多少个字母”之类的问题。

然后我决定添加使用报纸模块搜索最新消息的功能。

所有这些都有效，除非for循环完成，在打印字符串文字后，它给了我一个错误，我不知道这到底是什么意思。

有人可以为我破译错误，如果可能的话，帮我修复错误？谢谢。

这是错误：

好吧，我现在开始工作了，出于某种原因，我说：if (q != 'News'):我想要if (q != 'Latest News'):.

然后python为此向我抛出了一个错误。至少现在我让它工作了。
