Depending on the meaning of "effective", I suppose so. > In other words: Does .timetuple() create a tuple, or does it just return > a tuple which is present anyway? I don't know what it does. Normally one shouldn't care about that kind of thing. In this case, you seem to be assuming that .month and .day are values that are "present anyway", but we don't really know that either, since they could just as well be properties. If someone who knows or someone who checks the source (for a given implementation of course... it could change) cares to share, we'd know more. What good that would do us is still a mystery to me. ;-) -Peter -- http://mail.python.org/mailman/listinfo/python-list
