Hello everyone,
We are trying to implement our own interactive interpreter in our 
applicationusing an embedded Python interpreter.
I was wondering what would be the best way to retreive as text the result of  
executing Python code. The text must be exactly the same as it would be in 
thestandalone interpreter.
We used to do this by changing the embedded interpreter's sys.stdout and 
sys.stderrwith a FILE created in C++. We could then execute code using the 
PyRun_InteractiveOnefunction and easily retrieve the result from the FILE. The 
problem is, our applicationshouldn't create any files if possible.
We also tried replacing sys.stdout and sys.stderr with a custom made Python 
objectwhich could be more easily read from C++. We then used the function 
PyRun_Stringto execute the code. The problem here is that using the 
Py_file_input start tokendoesn't write everything we need to sys.stdout. (i.e. 
executing 2+2 does not write 4).It also doesn't print a traceback to sys.stderr 
when there is an exception. Using theother two start tokens is impossible since 
we need to be able to execute more than one instruction at once. We also tried 
using the function PyRun_SimpleString but weencounter the same problems.
We are using python 2.7. 
Any suggestions? 
Thank you for your time.
Also, I'm new to mailling lists, what is the proper way to reply to someone? 
Should Ireply directly to someone's email adress or is there a way to answer 
trough the server.
