If it's actually *console* output (performed through the Windows API
for doing console output), no. If it is, as in the following example,
output performed to standard-handles, then, yes, but you will have
to use os.popen rather than os.system.

If program.exe chooses to perform its output directly 'to the screen'
(via the Console API's of Windows, or other means, such as poking
into the simulated screen memory etc), you're out of luck. If it more
normally chooses to write to 'standard output', then run it via
xx=os.popen("program.exe","r") -- the returned xx object is a file
like object from which you can read from.
