问题就出现在条件选择上tr_list = soup.select('.context-box-text tr')，爬虫常遇到的问题就是网页一些选择条件经常变更，导致爬虫失效。

• tr_list = soup.select('tr[class="telerik-reTableOddRow-5"]')改成这个试试，选择单数行
• tr_list = soup.select('tr[class="telerik-reTableEvenRow-5"]') 偶数行，与单数行的class又不同，需要调整代码

并且实际上，我也只想要以上这些国家名称和排名数据。不需要导航栏，还有其他的。。奈何前端学的稀烂，不太会

bs 的 select 换成 telerik-reTable-5 tr 试试，感觉你的样式类名写错了
