You'll have to propose an implementation strategy for that which works without actually copying all the code, though. > Since x._hidden is not accessible from attack.py, the attack fails. But if _hidden were an attribute of the A instance that you were trying to protect, it would succeed. So you can't actually protect any direct attribute of a class that can be subclassed. Which means we're back to the situation of having to prevent access to class objects. -- Greg _______________________________________________ Python-Dev mailing list [email protected] http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
