我从beautifulsoup4中得到了

I get that from beautifulsoup4:

<tr class="Details"> <td class=" s-12-to-15 ">ABC</td> <td class="s-15-to-18 ">DEF</td> <td class=" s-18-to-21 ">GHI</td></tr>

我如何获得:

s-12-to-15 ABC
s-15-to-18 DEF
s-18-to-21 GHI

我研究了bf4文档和一些有关检索类名的堆栈问题，但没有成功.我无法检索这些类. (我知道我可以解析字符串以获取结果，但是我有兴趣了解bf4).

    print ''.join(s['class']).strip(), s.text
