I am trying to use PyObject_CallMe thod. It needs a format string to
specify what are the followed arguments. Is it possible to use a
PyObject* as an argument?
Where can I find the spec for the format?
Thanks in advance.

See http://docs.python.org/api/object.html#l2h-247 :
Note in particular "The C arguments are described by a Py_BuildValue()
format string that should produce a tuple" and "Note that if you only
pass PyObject * args, PyObject_CallMe thodObjArgs is a faster
alternative."
So, If all your arguments are PyObject pointers, use
PyObject_CallMe thodObjArgs instead. Otherwise, use PyObject_CallMe thod
and consult the documentation for Py_BuildValue on how to construct the
format string.
Hope this helps,
Carsten.
Thanks. I have mixed arguments.
I found the format spec @ http://docs.python.org/api/arg-parsing.html

Calling a python method from C++ has the following signature:
PyObject *
PyObject_CallMethod(PyObject *self, char *method_name,
char *arg_format, ...);
I'm having trouble figuring out how to declare self.
Let's say my python file is called stuff.py and is like the following,
doMath() is defined in stuff.py and is not part of any class:

I'm creating a web-based authoring tool where one form encompasses
several sections for editing. I'd like each section to have its own
reset button, so that use of that button affects only that section.
I can't find anything in the 4.0 spec about how to do this, and the
only mention in this group I found is from 1998 below (CERN blocked my
email to Alan).
I've tried wrapping each section in its own fieldset, but that had no
effect.

I am curious if there is something that would be considered a proper
method for locating small (three to four items) amounts of page specific
styling. Or does it really matter in the great scheme of things?
I have a linked style sheet that covers everything I want to do
globally. What should be done if I want to change and/or add a couple of
divs and paragraphs on a specific page and the style applied is specific
to that one page?
