Python code to consolidate CSS into HTML

Question

Looking for python code that can take an HTML page and insert any linked CSS style definitions used by that page into it - so any externally referenced css page(s) are not needed.

Needed to make single files to insert as email attachments from existing pages used on web site. Thanks for any help.

Sven's answer helped me, but it didn't work out of the box. The following did it for me:

import bs4   #BeautifulSoup 3 has been replaced
soup = bs4.BeautifulSoup(open("index.html").read())
stylesheets = soup.findAll("link", {"rel": "stylesheet"})
for s in stylesheets:
    t = soup.new_tag('style')
    c = bs4.element.NavigableString(open(s["href"]).read())
    t.insert(0,c)
    t['type'] = 'text/css'
    s.replaceWith(t)
open("output.html", "w").write(str(soup))
