How to solve the 'Segmentation fault' when hybrid programming of C & Python?

Question

Under my Ubuntu:

$ cat test.py

#Filename test.py 
def Hello(): 
    print \"Hello, world!\" 

$ cat tom.cpp

#inclu

The issue is caused by PyObject_GetAttrString returning NULL. I have also added the directory path using PyRun_SimpleString as my dev dir was not under python path

#include 

int main() {
    Py_Initialize();
    PyRun_SimpleString("import sys; sys.path.insert(0, 'add the directory path here')");
    PyObject * pModule = NULL;
    PyObject * pFunc   = NULL;

    pModule = PyImport_ImportModule("test");
    pFunc   = PyObject_GetAttrString(pModule, "Hello");
    if (pFunc != NULL) {
        PyEval_CallObject(pFunc, NULL);
        Py_Finalize();
    }
    else {
        printf("pFunc returned NULL\n");
    }

    return 0;
}
