export python code to cpp code example
Example: c++ call python function
int main() {
// Set PYTHONPATH TO working directory
setenv("PYTHONPATH",".",1);
PyObject *pName, *pModule, *pDict, *pFunc, *pValue, *presult;
// Initialize the Python Interpreter
Py_Initialize();
// Build the name object
pName = PyString_FromString((char*)"arbName");
// Load the module object
pModule = PyImport_Import(pName);
// pDict is a borrowed reference
pDict = PyModule_GetDict(pModule);
// pFunc is also a borrowed reference
pFunc = PyDict_GetItemString(pDict, (char*)"someFunction");
if (PyCallable_Check(pFunc)) {
pValue=Py_BuildValue("(z)",(char*)"something");
PyErr_Print();
printf("Let's give this a shot!\n");
presult=PyObject_CallObject(pFunc,pValue);
PyErr_Print();
}
else
PyErr_Print();
printf("Result is %d\n",PyInt_AsLong(presult));
Py_DECREF(pValue);
// Clean up
Py_DECREF(pModule);
Py_DECREF(pName);
// Finish the Python Interpreter
Py_Finalize();
