I don't think anyone will know exactly how 3.0 will look within 6 months. Not that your publisher may care about that; there are plenty of books out there that describe how the author thought something would look some time in the future. For some publishers, being bleeding edge is more fun than being useful. And you can always print a second edition. But if the goal is to be useful, I'd target 2.5, and mention differences and workarounds for 2.3 and 2.4 where suitable. </F> -- http://mail.python.org/mailman/listinfo/python-list
