Well there is always the slice object. slice(start, stop, step) Maybe if slice was more interchangeable with range or xrange, or if range objects could be used in place of slice objects? <shrug> A few results form Python 2.5:
s = slice(10, 20, 3)
range(s) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: range() integer end argument expected, got slice.
range(100)[s] [10, 13, 16, 19]
xrange(s) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: an integer is required
xrange(100)[s] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: sequence index must be integer, not 'slice'
list(xrange(100))[s] [10, 13, 16, 19]
