if isinstance(result, str): result = unicode(result) avoid repeating in Python a test already made in C by re-spelling it as result = unicode(result) or have you hand-waved away important details that mean the test really is required? regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC http://www.holdenweb.com/ _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
