No, the behavior _is_ undefined. The comment you cited says that it cannot crash the Python interpreter; additionally, it makes a best-effort attempt at catching such accesses and raising ValueError. But I think I can build a strange-looking example where you mutate a list during sorting and don't get a ValueError (although admittedly it needs a lot of hacking to do that nowadays, e.g. multiple threads). A bientôt, Armin. _______________________________________________ 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
