...unless you run Python with the -u option, which makes output
unbuffered (and, if on Windows where it matters, binary).  However, it's
not sufficient to ensure the user's browser will show the messages you
want when you want.  A much more reliable way to achieve that is to use
timed redirects, or an AJAX (Javascript-based) solution.
