Probably easier to use a couple of classes:

###
# interface.py
class Interface:
	def callback1(self, args):
		pass

###
# implementation.py
from interface import Interface

class Implementation(Interface):
	def callback1(self, args):
		do_some_junk()

###

Then in the C code do something like:

// N.B. This will leak a bit. Need to DECREF some stuff...
PyObject* mod = PyImport_ImportModule("implementation");
PyObject* dict = PyModule_GetDict(mod);
PyObject* imp_class = PyDict_GetItemString(dict, "Implementation");
PyObject* imp_inst = PyEval_CallObject(imp_class, PyTuple_New());
PyObject* callback1 = PyObject_GetAttrString(imp_inst, "callback1");
PyObject* result = PyEval_CallObject(callback1, Py_BuildValue("(s)",
"arg"));
