Maybe you could replace: "these are the start and stop indices and the step or stride length of the slice" with "these are start, stop and step values suitable for passing to range or xrange" I wanted to say something about what happens with a negative stride, to indicate that it produces (9, -1, -2) instead of (-1, -11, -2), but I wasn't able to navigate the Python documentation well enough. Looking at the Language Reference section on the slice type[1] (section 3.2), I find that "Missing or out-of-bounds indices are handled in a manner consistent with regular slices." So I looked for the documentation of "regular slices". My best guess was that this meant looking at the Language Reference on slicings[2]. But all I could find in this documentation about the "stride" argument was: "The conversion of a proper slice is a slice object (see section 3.2) whose start, stop and step attributes are the values of the expressions given as lower bound, upper bound and stride, respectively, substituting None for missing expressions." This feels circular to me. Can someone help me find where the semantics of a negative stride index is defined?
