BeautifulSoup - extracting attribute values

If Beautiful Soup gives me an anchor tag like this:

<a class="blah blah" id="blah blah" href="link.html"></a>

How would I retrieve the value of the href开发者_运维问答 attribute?

If you already have the anchor, grab the href attribute like this:

href = anchor["href"]

---

link.get('href')

in which 'link' is the name of your 'a' tag
