Another data point: on our six-figure loc code base, we have 123 instances of getattr, 30 instances of setattr, and 0 instances of delattr. There are 5 instances of setattr( ... getattr( ... ) ) on one line (and probably a few more that grep didn't pick up that span multiple lines). As a comparison, enumerate (that I would have believed was much more frequent a priori), is used 67 times, and zip/izip 165 times. +1 on .[] notation and the idea in general. -Mike _______________________________________________ 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
