Sure, but you'll have to display it yourself. My script usually look like

writeheader(req, mytitle . . .)
   # do some stuff (like connecting to the DB)
printfooter(req, . . .)

The printexception() routine is defined as:

def formatexception():
   info = sys.exc_info()
    result = "\n<HR>\n<P><B>%s:</B> %s</P>\n" % info[:2]
    if verbose:
        import traceback
        result += '<PRE>' + "\n".join(traceback.format_tb(info[2])) +
    return result

def printexception(req=sys.stdout):

The 'verbose' global variable can be turned off and on by sending a request
to the server.
