title: Extracting a 7-Zip file "silently" - command line option
body: <p>I want to extract a <a href="http://en.wikipedia.org/wiki/7-Zip" rel="noreferrer">7-Zip</a> archive in a Python script. It works fine except that it spits out the extraction details (which is huge in my case).</p>
  
  <p>Is there a way to avoid this verbose information while extracting? I did not find any "silent" command line option to <code>7z.exe</code>.</p>
  
  <p>My command is</p>
  
  <pre><code>7z.exe -o some_dir x some_archive.7z
  </code></pre>
