Hi,

is there any way how to execute the Python module function from char* bufer? Now I'm using the PyImport_Import to load the '.py' module but I would prefer to provide the char* buffer to the interpreter instead. I have found only the PyRun_SimpleString but it does not give me the flexibility of providing the input parameters and checking the result...

Thanks a lot,
BR

Do you mean you want to import a module, then call a function from that module? If so, you want something like...

Py_Initialize();

PyObject* module = PyImport_ImportModule("mymodule");
PyObject* func = PyObject_GetAttrString(module, "myfunction");
PyObject* result = PyObject_CallObject(func, NULL);

// Do something with 'result'

Py_DECREF(result);
Py_DECREF(func);
Py_DECREF(module);

Py_Finalize();

There's a more complete example at http://docs.python.org/extending/emb...pure-embedding.

If you meant something else, then please clarify.

Hi,

thanks for reply! |But I do not want to import module from file - this is already working for me. The problem is that when I use the PyImport_Import I need to have saved the Python script in the .py file. What I need is to construct the script body dynamically in C++ and provide it to the interpreter as a char* buffer... (of course I can save it to some tepmorary file, but this is not too nice solution). The only method I have found was PyRun_SimpleString - but it does not allow to handle complex scenarios with passing paramateres, readign result, etc.

I'm not sure I understand. If you want to generate a fixed char* buffer with the code, and then execute it, I don't see where the 'passing parameters' applies.

Unless you mean you want the Python module to call back into C functions, in which case you need to use a combination of embedding and extending.
