Tim Peters <t...@python.org> added the comment:
There are a number of "obvious" properties that should obtain, given the intended meaning of weights: - An input with weight 0 should never be returned. - The distribution shouldn't be affected by adding a new input with weight 0. - The distribution shouldn't be affected by removing an input with weight 0. Especially because of the 3rd, the only sensible thing to do is to treat an input with weights all 0 much like an empty population - although, in context, ValueError would make more immediate sense for "all weights are 0" than the IndexError raised for an empty population. Anything other than that is "too clever" by half, and I just don't believe would be of real use often enough to be worth violating the "obvious" properties above. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38881> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
