Python 去除汤中的特定项目

我怎样才能用python和beautiful soup去掉这些，剩下的就不用了，

td

中的其他项目需要保留

<td style="background:#aaccff" width="50"></td>
<td align="left" style="background:#aaccff" width="150">Device Type</td>
<td align="left" style="background:#aaccff" width="115">IP Address</td>
<td align="left" style="background:#aaccff" width="100">Device Name</td>
<td align="left" style="background:#aaccff" width="215">Notes</td>
<td width="50"></td>

这是电流输出

通常，当人们问如何使用

bs4

来“删除”某个东西时，他们实际上只是问如何在

find

操作中不包含它

您希望排除额外的空格（即带有

tag.text=''

的标记）和这四个“列标题”标记。您可以通过CSS选择器执行后者，但前者需要显式过滤。因此，同时做这两件事是最容易的，而且在我看来更具声明性：

soup = BeautifulSoup(that_long_html_you_gave)

blacklist = {'Device Type','IP Address','Device Name','Notes'}

table = soup.body # to match your variable name.  I think.

table.find_all(lambda tag: tag.text and tag.text not in blacklist)

soup=BeautifulSoup（你给的）

table=soup.body#以匹配变量名。我想。
table.find_all（lambda标记：tag.text和tag.text不在黑名单中）

你说的“删除”是什么意思？去掉它们，这样它们就不会在最终输出中显示。我不清楚为什么要选择要删除的标记和保留的标记。到目前为止，你的代码做了什么？要删除设备类型IP地址设备名称注释和额外的空格吗
