有一段HTML代碼<tr bgcolor="#cceeff" style="page-break-inside:avoid ; font-family:Def.-Times; font-size:8pt"><td colspan="3" valign="top"> <p style=" margin-top:0pt ; margin-bottom:0pt; margin-left:2.00em; text-indent:-1.00em; font-size:8pt; font-family:ARIAL"><b>{99}</b> <b></b>Receivables becoming Defaulted Receivables during period</p></td><td align="right" valign="bottom"><font style="font-family:ARIAL; ">1,310,326.05</font></td> <td nowrap="nowrap" valign="bottom"><font style="font-family:ARIAL; "> </font></td> <td valign="bottom"> </td> <td valign="bottom"></td> <td valign="bottom"></td>我怎樣才能提取數(shù)據(jù){4}Defaulted Receivables', '{4}', '1,310,326.05']我有一個(gè)人給我的代碼def get_row(soup, n): return [td.get_text(strip=True) for td in soup.select('tr:contains("{' + str(n) + '}") td') if td.get_text(strip=True)]但首先，我不明白如何在 HTML 代碼中查找“行”。其次， tr:contains("{' + str(n) + '}") td這段代碼是做什么的？抱歉，我對(duì)抓取和 HTML 還很陌生

我改進(jìn)/更正了代碼，現(xiàn)在它將打印每行的條目文本列表列表。
代碼需要一次安裝 beautiful soup 和 lxml：python -m pip install lxml bs4。
# Needs: python -m pip install lxml bs4
import lxml
from bs4 import BeautifulSoup
soup = BeautifulSoup("""
<tr bgcolor="#cceeff" style="page-break-inside:avoid ; font-family:Def.-Times; font-size:8pt">
<td colspan="3" valign="top"> <p style=" margin-top:0pt ; margin-bottom:0pt; margin-left:2.00em; text-indent:-1.00em; font-size:8pt; font-family:ARIAL"><b>{99}</b> <b></b>Receivables becoming Defaulted Receivables during period</p></td>
<td align="right" valign="bottom"><font style="font-family:ARIAL; ">1,310,326.05</font></td>
<td nowrap="nowrap" valign="bottom"><font style="font-family:ARIAL; "> </font></td>
<td valign="bottom"> </td>
<td valign="bottom"></td>
<td valign="bottom"></td>
</tr>
""", 'lxml')
print([[
td.get_text(strip=True) for td in tr.select('td') if td.get_text(strip=True)
] for tr in soup.select('tr')])
代碼打?。?/p>
[['{99}Receivables becoming Defaulted Receivables during period', '1,310,326.05']]
