range(start,stop)

Well, unless you made a mistake in your message, it does what you ask
already:

    >>> print range(0,9)
    [0, 1, 2, 3, 4, 5, 6, 7, 8]

If what you really meant was why doesn't range(start, stop) include stop in
its output, that has to do with consistent modulo arithmetic.  Others can
describe it better.  You might try searching the list archives.  I'm fairly
certain Tim Peters or GvR have expounded on this topic before.
