Since 'i' and 'j' are canonically loop indices, I find it totally confusing to use them to name the iteration variable - which is not an index. At least, 'item' suggests that it's an object, and a part of the collection - not just an index you'll have to use to subscript the container. Also, and as far as I'm concerned, I certainly dont find 'i' and 'j' *less* generic than 'item' !-) I agree that except for uber-generic code or quick throw-away script 'item' is probably not a very good name, but then nor are 'i' and 'j'... -- http://mail.python.org/mailman/listinfo/python-list
