You'll need to give us more information about the program you're trying to automate. It originally sounded like you just needed to run a console program, where it's usually fairly easy to run and capture the output with the subprocess module. Now it sounds like you're trying to automate a GUI that requires user interaction. That's quite a bit more complicated. When you run stats_hall.exe, what do you get on the screen? What, exactly, are the steps a normal user would need to perform to do what you want to automate? After the values you're interested in are computed, where do they show up? Is this program publically available someplace? I've generally had good luck doing simple GUI automation with pywinauto. The homepage appears to be: http://pywinauto.pbworks.com which has installation instructions and a FAQ.

If you are not already, I would highly suggest using Python3 with the
subprocess module:
http://docs.python.org/py3k/library/subprocess.html
It puts everything in one place and supercedes the exec* functions which
where a PITA. You can 95% of what you need simply using
subprocess.Popen(). There are several examples from this group in the past
few days; but, the process looks something like this:

Suggesting subprocess is a good idea, *highly* suggesting python3 is

Py3 is a better core language than py2, but for now, less featured.

How to run an EXE, with argument, capture output value
Hello All,
I would appreciate some guidance on this. I'm a newbe, sorry if I
sound dumb - I kind of am on this stuff!
I have an executable that I want to run within python code. The exe
requires an input text file, the user to click a 'compute' button, and
then the exe calculates several output values, one of which I want to
capture into a variable. Can I use Python to supply the input file,
execute the exe and capture the output value, like such that the exe
really doesn't need to be 'seen'? Or, would the user still have to
click the 'compute' button?
Any code snippets or guidance would be very much appreciated. I have
found that
import os
os.system('C:\xTool\stats_hall.exe')
will run the exe. And, maybe these execl/execle/execlp/etc functions
might be what I need for adding in the argument, but documentation
seems to indicate that these do not return output. ??
Thanks much.
