Your xslice (or mine) would still be better than islice when the step size is large; islice has to iterate over all the skipped elements which could be wasteful if the input is indexable. Also islice doesn't support negative values for start, stop or step which xslice does. -- http://mail.python.org/mailman/listinfo/python-list
