Peter Waller <peter.wal...@gmail.com> added the comment: Hi Amaury,
Thanks. I had heard of but never bothered to read about duck-typing before now; though I have used it passively before. I think it does make sense in this case. I can't imagine any case where checking for the _fields attribute would fail and isinstance(x, namedtuple) would not. Besides which, for my current project I am forced to implement such a "workaround" anyway, so it doesn't affect me as such. The only reason that remains why I would want it is that I often use isinstance(x, Y) to deal with different Ys, and that was the thing I intuitively wanted to use in this case as a python programmer for quite a few years now. This is probably a pretty weak reason, so I am happy to close this issue if the consensus points to duck typing. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7796> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
