title: Suppressing output in python subprocess call
body: <p>For the following command:</p>
  
  <pre><code>subprocess.call(shlex.split(
              """/usr/local/itms/bin/iTMSTransporter -m lookupMetadata 
                -apple_id %s -destination %s"""%(self.apple_id, self.destination))
  </code></pre>
  
  <p>It prints the entire output into the Terminal window. How would I suppress ALL output here? I tried doing <code>subprocess.call(shlex.split(&lt;command&gt; &gt; /dev/null 2&amp;1</code>)), but it didn't produce the required results. How would I do this here?</p>
