Suppress verbose output of shell command in python

I am running a shell command in a python script which installs ruby and rubygems using the subprocess function:

subprocess.call("yum install ruby rubygems -y  2>&1", shell=True)

In this however, the 2>&1 doesn't seem to suppress the output like in a normal bash script. Is there any other way to suppress the output?

You forgot this:

1>/dev/null

So, the result script will be:

subprocess.call("yum install ruby rubygems -y  2>&1 1>/dev/null", shell=True)

If you really need to do this then - Use subprocess.Popen with stdout and stderr redirected to pipes.
