How to send more data to python

• To see these techniques in use view Strategy.cc. the pyFunction.
• the first command that must be run before using or calling python Scripts or PyObjects is Py_Initialize(). this function basically creates a python interpreter to run python commands and files
• to run a python command use the following command PyRun_SimpleString("import os"). in this example here we are importing the os library to interpreter.
• this is an example on how you can call on a python file. to check if it has imported you can put pModule in an if statement

//calling on myFile.py 
PyObject *  pName = PyUnicode_FromString("myFile");
PyObject * pModule = PyImport_Import(pName);

if(pModule)
{
	// running the method myFunc in myFile.py
	PyObject * pFunc = PyObject_GetAttrString(pModule, "myFunc"); 
       
	if(pFunc && PyCallable_Check(pFunc))
	{
           //here we call on the python function and store the output in a PyObject in this example we are sending in a list so we attach an O before world_data
           PyObject * pReturn = PyObject_CallFunction(pFunc,"O",world_data);
	   //here we convert the pyobject to the relevent c++ format
           int x = (int) PyLong_AsLong(pReturn);
	   return x;
	}
	else
	{
            
	    cout << "ERROR: function selectSkill()\n"<<endl;
            return -1;
	}

	}
	else
	{
        
		cout << "ERROR: Module not imported"<<endl;
        return -2;
	}

for info on how to convert c++ to PyObject look here and how to convert from PyObject to c++ you can look here

• an example of converting a c++ data type to a python Object

//converting an integer to a PyObject
int x = 5
PyObject * temp;
temp = Py_BuildValue("i",x);

• an example of extracting data from a PyObject

PyObject * objectPy;
//update objectPy
int x = (int) PyLong_AsLong(objectPy);

### Handling Python Lists 
* how to define a python list
```C++
int n = 5;
PyObject* pyList = PyList_New(n);

• how to get an item from the pyList (get the item at index 0)

PyObject* item = PyList_GetItem(pyList, 0);

• how to set an item in a python list

int value = 5;
PyObject * item = Py_BuildValue("i",value);
PyList_SetItem(PyList,0,item);
