<a class="commentsCount" href="http://www.thehindu.com/news/cities/Delhi/power-discoms-demand-yet-another-hike-in-charges/article4331482.ece#comments">
</div>
我需要为类<a href=>获取所有div的article-additional-info值
我是BeautifulSoup的新手
所以我需要网址
"http://www.thehindu.com/news/national/gangrape-case-two-lawyers-claim-to-be-engaged-by-accused/article4332680.ece"
"http://www.thehindu.com/news/cities/Delhi/power-discoms-demand-yet-another-hike-in-charges/article4331482.ece"
实现这一目标的最佳方法是什么？

根据您的标准，它返回三个网址（而不是两个） - 您想过滤掉第三个网址吗？
基本思想是遍历HTML，只抽取你班级中的那些元素，然后遍历该班级中的所有链接，拉出实际的链接：
In [1]: from bs4 import BeautifulSoup
In [2]: html = # your HTML
In [3]: soup = BeautifulSoup(html)
In [4]: for item in soup.find_all(attrs={'class': 'article-additional-info'}):
...: for link in item.find_all('a'):
...: print link.get('href')
...:
http://www.thehindu.com/news/national/gangrape-case-two-lawyers-claim-to-be-engaged-by-accused/article4332680.ece
http://www.thehindu.com/news/cities/Delhi/power-discoms-demand-yet-another-hike-in-charges/article4331482.ece
http://www.thehindu.com/news/cities/Delhi/power-discoms-demand-yet-another-hike-in-charges/article4331482.ece#comments
这会将您的搜索范围限制为仅包含article-additional-info类标记的元素，并在其中查找所有锚点（a）标记并抓取其对应的href链接。

from bs4 import BeautifulSoup as BS
html = # Your HTML
soup = BS(html)
for text in soup.find_all('div', class_='article-additional-info'):
for links in text.find_all('a'):
print links.get('href')
打印哪些：
