The username and password need to go in an "Authorization" header.
Something like this should work:

    import base64
    import string
    import httplib

    userid = "foo"
    passwd = "bar"

    # "Basic" authentication encodes userid:password in base64. Note
    # that base64.encodestring adds some extra newlines/carriage-returns
    # to the end of the result. string.strip is a simple way to remove
    # these characters.
    auth = 'Basic ' + string.strip(base64.encodestring(userid + ':' + passwd))

    h = httplib.HTTP(Server)
    h.putrequest('GET', Page)
    h.putheader('Authorization', auth )
    h.endheaders()

Hope that helps...
