You might be interested in this article and the associated logintools,
either as an example or to use directly:
http://www.voidspace.org.uk/python/articles/cgi_web_applications_two.shtml#who-are-you
http://www.voidspace.org.uk/python/cgi.shtml#login
According to the article you need to add
if os.environ.has_key('HTTP_COOKIE'):
thiscookie.load(os.environ['HTTP_COOKIE'])
to your main() before you try to access the cookie values.
