I think you are. I would describe the above as a shallow copy, not a deep copy. I expect a deep copy to go *all the way down*, as deep as possible. Even if it makes no practical difference, I think it will be less confusing to just describe it as a "copy" rather than a deep copy, unless you recursively copy everything all the way down. -- Steven _______________________________________________ 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
