There is actually a logic to that. It's explained in the help/tutorial file, that you should think about the index as a cursor, the index itself doesn't point to the item itself, but to the interval between the item. (read this on a monospace font, or it'll look screwed up) 0 1 2 3 4 5 +-------------------+ | A | B | C | D | E | +-------------------+ -5 -4 -3 -2 -1 0 So to get BCD, you say [1:4] -- http://mail.python.org/mailman/listinfo/python-list
