Question

I need to save output in Python.

Example:

import os

ob_start();
os.system( 'c:\files\file.exe' );
var = ob_content();
ob_close();
print "message:\n\t" + var

Answer 1

You need to use the subprocess module and pass stdout and stderr via pipes back to your calling process using a Popen object (make sure to read the docs on which convenience methods you should not use with pipes on stdout or stderr). os.system is a pretty one-dimensional hammer, and while easy to use simply won’t do what you want.
