I'm using the os.system command in a python script on Windows to run a
batch file like this:

os.system('x.exe')

The third-party program x.exe outputs some text to the console that I
want to prevent from being displayed. Is there a way to prevent the
output of x.exe from python?

Check out the subprocess module. With it you can control more than
with os.system().

Use os.popen('x.exe') instead.

using the subprocess module to create a subprocess and piping the
stdout,stdin and stderr so you wont see any ouput from the process
unless you read from the PIPE's.


import subprocess
p = subprocess.Popen("x.exe", shell=True,
stdout=subprocess.PIPE,stdin=subprocess.PIPE, stderr=subprocess.PIPE)

This seems like the right thing to do, but it runs the program in the
background, and I need my program to wait until the x.exe has finished.
I tried using this code:

p =
subprocess.Popen("x.exe",shell=True,stdout=subproc ess.PIPE,stdin=subprocess.PIPE,
stderr=subprocess.PIPE)
sts = os.waitpid(p.pid, 0)

But I get the error: "No child process". Any ideas?

Read the docs.

Here's a link to the docs for the subprocess.Popen object. Note the
second method? http://docs.python.org/lib/node239.html

Is .exe really a batch file?

To consign stdout to nul in MSDOS you can use os.system('x.exe>nul')
so that will probably work for windows, too. This works regardless
of x.exe or x.bat so should do for whatever type of prog you are wanting
it for.
