我有一些这种形式的HTML:
<td class=Test">
<a href="www.randomsite.com"> </a>
<font>Text</font>
</td>
在我的BS中,我试图将其更改为:
<td class=Test">
<a href="www.randomsite.com"> </a>
<font><h2>Text</h2></font>
</td>
请注意,字体中的文本周围添加了<h2>
个标记。
然而,对于每个文件,它似乎创建了两个额外的文件,这两个文件都没有按照我的希望正确标记。例如,如果我的某个文件是file1.html
,则此代码会创建file1_mod.html
和file1_mod_mod.html
可能导致这种情况的原因是什么?我已经尝试在PyCharm中逐步执行该文件,但我仍然相对较新的BS / Python,因此调试是一个痛苦的过程。
