Stephen J. Turnbull added the comment: I prefer Josh's wording. The important point to me is that
>>> [1, 2][2:0] = "AB" [1, 2, "A", "B"] not an error or ["B", "A"] == [1, 2][2:0:-1]. I think too much talk about the endpoints obscures this important fact. (I think I'd like it to be an error, since the interpretation of s[2:0] = t could reasonably be any of s[0:0] = t, s[1:1] = t, or s[2:2] = t, but I haven't thought carefully enough yet, and "backward compatibility".) Note: Josh's wording is already used in 3.7 (https://docs.python.org/dev/library/stdtypes.html#common-sequence-operations, as of the timestamp of this message). I didn't check if it's been backported. ---------- nosy: +sjt _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29352> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
