These proposals probably should be discussed on Python-Ideas first. You should also familiarize yourself with previous proposals to enhance range, such as https://mail.python.org/pipermail/python-ideas/2018-November/054510.html and the bug report #35200 For what it is worth, Guido was generally (slightly) opposed to "constant bool parameters", functions that take a parameter which is generally given as a literal True/False flag. That's often (not always) a design smell. I agree with him, so I would be very wary about adding not one but two such constant bool parameters. Especially for such a trivial enhancement. There's nothing in the `inc_start=True, inc_stop=False` functionality which can't be more easily done by simply adding one to the appropriate range arguments: # same as inc_start=False, inc_stop=True but easier range(start+1, end+1) You say: "a mix of round parentheses and square brackets could be allowed" but I think such a proposal would run foul of the requirement that Python's grammar be no more complex than LL(1). (Someone will correct me if I'm wrong.) ---------- nosy: +steven.daprano _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35575> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
