python - 在 html 中搜索颜色标签(Python 3)

Question

如果单元格具有某种颜色，我试图从表格中获取元素。唯一的问题是，对于颜色标签，抓取颜色似乎还不太可能。

jump = []

for tr in site.findAll('tr'):
  for td in site.findAll('td'):
    if td == 'td bgcolor':
      jump.append(td)

print(jump)

这将返回一个空列表

如何从下面的 html 中获取颜色？

我需要从 [td] 标签获取颜色(从 [tr] 标签获取颜色也很有用)

<tr bgcolor="#f4f4f4">
<td height="25" nowrap="NOWRAP">&nbsp;CME_ES&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;07:58:46&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;Connected&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;0&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;0&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;0&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;0&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;07:58:00&nbsp;</td>
<td height="25" nowrap="NOWRAP" bgcolor="#55aa2a">&nbsp;--:--:--&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;0&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;0&nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp;01:25:00 &nbsp;</td>
<td height="25" nowrap="NOWRAP">&nbsp; 22:00:00&nbsp;</td>
</tr>

Answer 1

这个怎么样:

jump = []

for tr in site.findAll('tr'):
  for td in site.findAll('td'):
    if 'bgcolor' in td.attrs:
      #jump.append(td)
      print(td.attrs['bgcolor'])

print(jump)
