从C++调用Python

我试图从我的C++程序中调用一个Python脚本中的函数。python函数以字符串作为参数,不返回任何内容(ok..'None')。 只要在再次调用函数之前完成上一次调用,它就可以很好地工作(没想到会那么容易…),否则在 pModule = PyImport_Import(pName)

int callPython(TCHAR* title){
    PyObject *pName, *pModule, *pFunc;
    PyObject *pArgs, *pValue;

Py_Initialize();
    pName = PyUnicode_FromString("Main");
    /* Name of Pythonfile */

    pModule = PyImport_Import(pName);
    Py_DECREF(pName);

if (pModule != NULL) {
        pFunc = PyObject_GetAttrString(pModule, "writeLyricToFile");
        /* function name. pFunc is a new reference */
        if (pFunc && PyCallable_Check(pFunc)) {
            pArgs = PyTuple_New(1);

    pValue = PyUnicode_FromWideChar(title, -1);

    if (!pValue) {
        Py_DECREF(pArgs);
                Py_DECREF(pModule);
        showErrorBox(_T("pValue is false"));
        return 1;
            }
    PyTuple_SetItem(pArgs, 0, pValue);

            pValue = PyObject_CallObject(pFunc, pArgs);
            Py_DECREF(pArgs);

            if (pValue != NULL) {
                //worked as it should!
                Py_DECREF(pValue);
            }
            else {
                Py_DECREF(pFunc);
                Py_DECREF(pModule);
                PyErr_Print();
        showErrorBox(_T("pValue is null"));
        return 1;
            }
        }
        else {
            if (PyErr_Occurred()) PyErr_Print();
            showErrorBox(_T("pFunc null or not callable"));
        return 1;
        }
        Py_XDECREF(pFunc);
        Py_DECREF(pModule);
    }
    else {
        PyErr_Print();
        showErrorBox(_T("pModule is null"));
    return 1;
    }
    Py_Finalize();
    return 0;
}
