Why bother? You can just put your Python script into a CGI-enabled server like you do with PHP:

    #!/usr/local/bin/python2
    import cgi
    print "Content-type: text/html\n\n"
    query = cgi.FieldStorage()
    if "name" in query:
        print "Hello, %s!" % query["name"].value
    else:
        print """
        <p>Insert your name and hit Go! to get greeted!</p>
        <form action='/cgi-bin/hello-py.cgi' method='get'>
          <input type='text' name='name'/>
          <button type='submit'>Go!</button>
        </form>"""

chmod 750 and go.
