There has been a rumor that range will effectively become xrange in Python 300 http://www.python.org/doc/essays/ppt/accu2006/Py3kACCU.ppt but range has always been iterable---did you mean to say "iterator"? but xrange objects to not support a next() method either---and as of Python 2.5 xrange is not deprecated (unless the documentation somehow got out of sync). http://docs.python.org/lib/built-in-funcs.html
My impression was that the traditional range returned a list and then the iteration proceeded over the list, and that has changed, just as it is no longer necessary to use the xreadlines method for files to iterate over the lines. I don't recall where I read this stuff. Hmm, but maybe you are right, that this is planned for python 3.0 but maybe not yet in current versions of python. From a ppt presentation by Guido: dict.keys(), range(), zip() won't return lists killing dict.iterkeys(), xrange(), itertools.izip() Chuck
