Using subprocess in python3 to get output of a command

Question

Hi Friends. I am writing a python3 script for audacious to check the internet for album cover of the current playing song and then display it in conky. I am trying to call a command from python and get it's output:
audtool current-song-tuple-data album
but when i use this command in python like this:
subprocess.check_output(["audtool", "current-song-tuple-data album"])
i get the following error:
Unknown command "current-song-tuple-data album".  Try "audtool help".
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.2/subprocess.py", line 522, in check_output
    raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '['audtool', 'current-song-tuple-data album']' returned non-zero exit status 1
Please , python experts on this forum, help me.

@Pranavg1890: Please add solved to your thread title then.
BTW: I found pexpect a good option for interacting with shell commands:
http://sourceforge.net/projects/pexpect/
It provides an easy way to deal with console output and react on certain patterns.
