Or if you don't want to use any 3rd party package and have Python 2.5,
you may start from http://www.xml.com/pub/a/2006/09/27/introducing-wsgi-pythons-secret-web-weapon.html.
Here's the standard "Hello world!" example:

from wsgiref.simple_server import make_server

def application(environ, start_response):
    start_response('200 OK',[('Content-type','text/html')])
    return ['<html><body>Hello World!</body></html>']

httpd = make_server('', 8000, application)
print "Serving HTTP on port 8000..."
httpd.serve_forever()

and point your browser to http://localhost:8000/

HTH,
