Me, too. There are plenty of things that aren't strictly a sequence, but which you sometimes want to iterate over anyhow. If I had a set of fast, overpriced luxury cars in my garage, I would sometimes want to do something to each one (like wash them), even though they really aren't in any sequence. Dictionary keys are the same sort of thing. Even though they aren't in any sequence, it's still useful to iterate over them. -- Neil Cerutti -- http://mail.python.org/mailman/listinfo/python-list
