Question

我正在尝试为Reddit创建一个用于抓取图像URL的机器人，使用simpleCV查找面部并在脸部周围裁剪，然后锐化并增强剩余的图像。但是当我试着在评论中找到URL时，我遇到了一个问题。我不得不尝试几种不同的方式使代码在完全不同的布局中工作，但似乎没有任何工作。我似乎遇到了urllib和urllib2的大部分问题。

当我使用urllib2时，它会告诉我“列表对象没有'超时'属性”或者没有超时属性的东西。我并不想要超时，只要它需要得到它，我就可以获得该文件。当我去使用urllib时，我遇到了一个关于“set object has no attribute'trip'”的错误。

我开始对此我的结束了，但我想完成它。有人能帮助我吗？此外，如果有人因语法需要编辑此问题，请继续。我不太擅长标点符号。

这是我的代码：

如何在reddit评论中获取链接并继续打开它？
