Discussed this with GvR. Here's a recap: For 2.6 and 3.1 which are already released, check for the _fields attribute. This is a guaranteed part of the API is not fragile. For the C structures, check for the n_fields attribute. In the future, the C API needs to grow to match the namedtuple() API and we should add an abstract base class describing the common API. Then you'll be able to write: if isinstance(obj, abc_namedtuple). ---------- _______________________________________ 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
