Serhiy Storchaka added the comment: "O" is not the only special case. "S" and "N" unpack a tuple argument too. "O&" converter should return a tuple, otherwise it is an error. All other format codes are illegal for single argument.
I would just deprecate this feature (in PyObject_CallFunction, not in Py_BuildValue). The behavior of PyObject_CallFunction with a single argument can be made more consistent and useful. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28977> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
