New submission from r3m0t: http://docs.python.org/3.3/c-api/structures.html#METH_KEYWORDS "Methods with these flags must be of type PyCFunctionWithKeywords. The function expects three parameters: self, args, and a dictionary of all the keyword arguments. The flag is typically combined with METH_VARARGS, and the parameters are typically processed using PyArg_ParseTupleAndKeywords()." The documentation doesn't mention the args/dictionary arguments will be NULL when there are no positional/keyword arguments. It might also be worth mentioning the arguments are in effect "borrowed" references. ---------- assignee: docs@python components: Documentation messages: 177341 nosy: docs@python, r3m0t priority: normal severity: normal status: open title: Poor documentation for METH_KEYWORDS versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue16663> _______________________________________
