Simpler still, just use di.keys() but make sure you're only using the result to iterate over once without modifying the dict's key set. Or if you *have* to avoid creating a list in Py2.x, write your code to iterate over the dict itself even if you'd like itervalues or iteritems; you can always get the value explicitly by indexing the dict. IOW use the API whose name will remain but don't rely on the functionality that will change. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ 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
