It says

> csv.reader(csvfile[, dialect='excel'][, fmtparam])
> csv.writer(csvfile[, dialect='excel'][, fmtparam])

in 2.7. I presume it should be like in 3.x:

> csv.reader(csvfile, dialect='excel', **fmtparams)
> csv.writer(csvfile, dialect='excel', **fmtparams)

Or am I missing something?

(I found argument renaming to be too invasive for my default-args-notation ticket #14804)

I verified from the source that it should be **fmtparams also in 2.7. Make sure you change the description texts, too, to s/fmtparam/fmtparams/.

Chris: Thanks for the patch. I'm not sure register_dialect()'s signature is good like that, though. Hynek, what do you think?

What does bother you? Both sigs look like in py3 if I'm looking correctly.

Well, I wasn't sure about [optional] params before **kwargs. But if that's ok, then I think the patch is good.

It seems correct like that:

static PyObject *
csv_register_dialect(PyObject *module, PyObject *args, PyObject *kwargs)
    PyObject *name_obj, *dialect_obj = NULL;
    PyObject *dialect;

    if (!PyArg_UnpackTuple(args, "", 1, 2, &name_obj, &dialect_obj))
        return NULL;

Therefore going to commit.
