I was considering suggesting this, but I'm not sure there is much hope that this would work. The posted code suggests that Townshps.next() returns "" or None when the end of the list is reached. In order for the for loop to work, it would have to raise StopIteration instead. (I suppose it is conceivable that iter(Townshps) would return an object that does behave in the required manner, but I wouldn't bet a lot of money on that.) Of the course if Townshps does not support the iteration protocol, the for loop could still be written using the iter(callable,sentinel) pattern, but let's not confuse this poor newbie more than necessary ;) -Carsten -- http://mail.python.org/mailman/listinfo/python-list
