我创建了下面的代码，但是如何通过用“,”分隔来更容易地以更易于理解的方式显示层次结构？

index_template.tpl

<html>
   <ul>
       %for item in links:
         <li>{{item}}</li>
       %end
   </ul>
</html>

输出结果

・{'http://www.oreilly.com/careers/', 'http://www.oreilly.com/about/editorial_independence.html', 'https://cdn.oreillystatic.com/pdf/oreilly_high_performance_organizations_whitepaper.pdf', 'https://www.youtube.com/user/OreillyMedia', 'https://www.safaribooksonline.com/?utm_medium=content&amp;utm_source=oreilly.com&amp;utm_campaign=lgen&amp;utm_content=20170601+nav'}
・{'http://www.oreilly.com/careers/', 'http://www.oreilly.com/about/editorial_independence.html'} 
・{'http://www.oreilly.com/careers/', 'http://www.oreilly.com/about/editorial_independence.html', 'https://cdn.oreillystatic.com/pdf/oreilly_high_performance_organizations_whitepaper.pdf', 'https://www.youtube.com/user/OreillyMedia'}

您的 links 对象是 set 的 list，您可以使用嵌套的 for 循环对其进行迭代：

<html>
    <ul>
    % for link in links:
        % for item in link:
        <li>{{item}}</li>
        % end
    % end  
    </ul>
</html>

输出：
