In C++ PythonQT, How to the variable name used in each thread is the same, but how do you use the value differently?

Question

I am using multithreading PythonQT in C++.
When using values of the same name in different threads, I want to use different values.
Help me plz...

[Code : run multithreading]

int nRet = PyEval_ThreadsInitialized();
if (Py_IsInitialized() == 0)
{
    Py_Initialize();
    PyEval_InitThreads();
    m_pyMainThread = PyEval_SaveThread();
}

std::shared_ptr<PythonWorkerThread> pythonWorker1 = std::make_shared<PythonWorkerThread>();
std::shared_ptr<PythonWorkerThread> pythonWorker2 = std::make_shared<PythonWorkerThread>();
pythonWorker1->setObjectName("1");
pythonWorker2->setObjectName("2");
pythonWorker1->start();
pythonWorker2->start();

[Code : run WorkerThread]

void PythonWorkerThread::run()
{
    qDebug() << "Thread Run = " << objectName() << " ThreadID = " << (int)QThread::currentThreadId();

    auto state = PyGILState_Ensure();

    for (int i = 0; i < 10; ++i)
    {
        PythonQt::self()->addVariable(PythonQt::self()->getMainModule(), "SharedValue", i);
        QString strScrip = QString("import time\n" "time.sleep(%1)\n").arg(objectName().toInt());
        PyRun_SimpleString(strScrip.toStdString().c_str());
        qDebug() << "Thread = " << objectName() << ", i =" << i << PythonQt::self()->getMainModule().getVariable("SharedValue");
    }
    PyGILState_Release(state);
    qDebug() << "Thread End" << objectName();
}
