如何使用 Python 3 抓取每个 td 标签内容

我要分析的内容如下图：

<tr>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">1470-160X</td>

<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;"><a href="http://www.letpub.com.cn/index.php?journalid=2408&amp;page=journalapp&amp;view=detail" style="color:#0099FF; font-size:12px; font-weight:bold; text-decoration:underline;" target="_blank">ECOLOGICAL INDICATORS</a><br><br><font color="grey">ECOL INDIC</font></br></br></td>

<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">3.190</td>

<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">2区</td>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">环境科学与生态学</td>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">环境科学</td>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">SCIE</td>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">No</td>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">容易</td>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">约3.0个月</td>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;"><a href="http://www.letpub.com.cn/index.php?page=journalapp&amp;view=detail&amp;journalid=2408&amp;xuanxiangk_id=2#xuanxk_3" style="color:#0099FF; text-decoration:underline;" target="_blank">文章</a>
<td style="border:1px #DDD solid; border-collapse:collapse; text-align:left; padding:8px 8px 8px 8px;">33977</td></td>

</tr>

你还可以看到截图（一个演示）：

内容并将其添加到相应的列表中。

我的代码片段如下：

journal_ISSN = []
journal_name = []
journal_affecting_factors = []
journal_JCR_zone = []
journal_parent_class = []
journal_sub_class = []
journal_SCI = []
journal_acception = []
journal_period = []

for i in range(2, 3):
url = "http://www.letpub.com.cn/index.php?page=journalapp&view=search&searchname=&searchissn=&searchfield=&searchimpactlow=&searchimpacthigh=&searchimpacttrend=&searchscitype=&searchcategory1=%E7%8E%AF%E5%A2%83%E7%A7%91%E5%AD%A6%E4%B8%8E%E7%94%9F%E6%80%81%E5%AD%A6&searchcategory2=%E7%8E%AF%E5%A2%83%E7%A7%91%E5%AD%A6&searchjcrkind=&searchopenaccess=&searchsort=relevance&searchsortorder=desc&currentsearchpage="
resp = urlopen('%s%d%s' % (url, i, 
soup = BeautifulSoup(resp, "html.parser")


journal_table = soup.findAll("table", {"class": "table_yjfx"})
# rows = journal_table.find_All("tr")[1:]
print(journal_table)

for line in journal_table:
    rows = line.findAll('tr')
    for single_line in rows[1:10]:
        col = single_line.findAll('td')
        journal_ISSN.append(col[0].string.strip())
        journal_name.append(col[1].string.strip())
        journal_affecting_factors.append(col[2].string.strip())
        journal_JCR_zone.append(col[3].string.strip())
        journal_parent_class.append(col[4].string.strip())
        journal_sub_class.append(col[5].string.strip())
        journal_SCI.append(col[6].string.strip())
        journal_acception.append(col[7].string.strip())
        journal_period.append(col[8].string.strip())

没有办法完成它。任何人都可以帮忙吗？

我收到了错误消息：

AttributeError: 'ResultSet' 对象没有属性 'string'
