如何修复 IndexError：列出此代码的索引超出范围

Question

我正在尝试创建具有正确名称的实时 Rapidvideo 链接。我在 github( https://github.com/robinjainher/kiss-gui-batch/blob/master/RV_downloader2.py ) 中找到了此代码。但它给出了一个 IndexError ：列表索引超出范围。整个代码可以在这里找到（ https://raw.githubusercontent.com/robinjainher/kiss-gui-batch/master/RV_downloader2.py ）

如果有人可以帮助我，我会很高兴。谢谢..
