PyRun_String with Py_single_input to stdout?

[stuart.tett@gmail.com]

I'm using PyRun_String with Py_single_input for a python interpreter
embedded in my application. I'm using Py_single_input . Py_single input
is what I want, but it seems to output to stdout. Before when I was
using Py_eval_input I was able to grab the result so I could print it
in a text box:

PyObject *resultObject = PyObject_Str( rstring );
if( resultObject != NULL ) {
char *string = PyString_AsStri ng( resultObject );
}

But Py_eval_input is only for isolated evaluation, not what I want.
Py_single_input gives "None" for the string.

I wrote a class that redirects std::cout, but this doesn't work for
this, I'm guessing because it uses printf to stdout, not cout.

Anyone know how I can get the string so I can print it in a text box.

Maybe because it actually returns None?

From your description this should be working... try posting some more code
showing how you call PyRun_String and how you process the result...

I found a solution using sys.displayhook here:

No it doesn't. I know the function returns something because when I
used Py_eval_input, it returned the correct output. The only
difference is thate Py_string_input outputs using sys.write (stdout)
