static PyMethodDef moduleMethods [] = {
     ...
};

statichere PyTypeObject MyClassType = {
     PyObject_HEAD_INIT (NULL)
     ...
};

initmymodule ()
{
     PyObject* module;
     PyObject* dict;

     module = Py_InitModule4 ("mymodule", moduleMethods,
           "doc string", NULL, PYTHON_API_VERSION);
     if (module == NULL) {
         return;
     }
     dict = PyModule_GetDict (module);
     PyDict_SetItemString (dict, "MyClass"),
         (PyObject*) &MyClassType));
