我使用python.org的教程 “将Python嵌入另一个应用程序”

如何检索调用C语言函数的Python模块的名称：

static int numargs=0;

/* Return the number of arguments of the application command line */
static PyObject*
emb_numargs(PyObject *self, PyObject *args)
{
    if(!PyArg_ParseTuple(args, ":numargs"))
        return NULL;
    return Py_BuildValue("i", numargs);
}

static PyMethodDef EmbMethods[] = {
    {"numargs", emb_numargs, METH_VARARGS,
     "Return the number of arguments received by the process."},
    {NULL, NULL, 0, NULL}
};

我已经将python嵌入到我的C ++应用程序中。但需要动态添加模块。与

Py_InitModule("module1", EmbMethods);
Py_InitModule("module2", EmbMethods);

相同的回调

static PyMethodDef EmbMethods[] = {
    {"some_func", some_func, METH_VARARGS,""},
    {NULL, NULL, 0, NULL}
};

需要这样的东西

static PyObject* some_func(PyObject *self, PyObject *args)
{
     char *p;
    if(!PyArg_ParseTuple(args, "s",&p))
        return NULL;

    std::cout<<self->module_name //<<<<<<<< self always == NULL , why?

    return Py_BuildValue("i", numargs);
}

python脚本

import module1
print module1.some_func()
print module2.some_func()

预期产量：＆＃34;模块1＆＃34; ＆＃34;模块2＆＃34;
