Import module after Py_Initialize

Question

Today, I use PyImport_AppendInittab to append python modules built in C. PyImport_AppendInittab needs to be called before Py_Initialize. I can't finalize and then initialize the engine again. The problem is that now I need to append some modules after Py_Initialize. Is there a way to do it?

I'm using Python 3.6.

Solved the problem by doing this:

if (Py_IsInitialized()) {
    PyImport_AddModule(module_name);
    PyObject* pyModule = moduleInitFunc();
    PyObject* sys_modules = PyImport_GetModuleDict();
    PyDict_SetItemString(sys_modules, module_name, pyModule);
    Py_DECREF(pyModule);
}
