View Full Version : Embedding Python in C++

So how can I do this:

Load 5 Python scripts
Pre-compile the scripts for fast executing
Run each script many times in isolated environments

I have read some tutorials about but no idea how to do it.

This should explain everything: http://www.python.org/doc/2.5.2/ext/embedding.html

How can I import Python modules from sub-folders?

Python gives ImportError when I try to load the scripts.

PyObject *filename, *py_script, *function;

filename = PyString_FromString( "data/python/script.py" );

py_script = PyImport_Import( filename );

Py_DECREF( filename );

if ( py_script == NULL )
function = PyObject_GetAttrString( py_script, "hello" );

Edit: Got working with this after Py_Initialize():

PyRun_SimpleString( "from sys import path\nfrom os import getcwd\npath.append( getcwd() + \"/data/python\" )\n" );

Without ugly \n's:

from sys import path
from os import getcwd
path.append( getcwd() + "/data/python" )
