How can I add background color inside html code using beautifulsoup?

Question

With beautifulsoup I get the html code of a site, let say it's this:

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>

How I can add this line body {background-color:#b0c4de;} inside the head tag using beautifulsoup?

Lets say python code is:

#!/usr/bin/python

import cgi, cgitb, urllib2, sys
from bs4 import BeautifulSoup

site = "www.example.com"
page = urllib2.urlopen(site)
soup = BeautifulSoup(page)

You can use:

soup.head.append('body {background-color:#b0c4de;}')

But you should create a <style> tag before.

For instance:

head = soup.head
head.append(soup.new_tag('style', type='text/css'))
head.style.append('body {background-color:#b0c4de;}')
