In the Python 2.6.4 documentation "2. Built-in Functions" at http://docs.python.org/library/functions.html, the section about the xrange function (paragraph "CPython implementation detail") contains the following code: islice(count(start, step), (stop-start+step-1)//step) However, count only accepts one parameter, so that this solution does not work. Furthermore, islice only accepts positive values for step. Therefore, the code does not work. I tested this with Python 2.5.4 and Python 2.6.4 on Debian Linux (AMD64).
