title: Extract a column from a string in Python
body: <p>I run a command remotely using Python and this is the output I get:</p>
  
  <pre class="lang-none prettyprint-override"><code>Vserver   Volume       Aggregate    State      Type       Size  Available Used%

  </code></pre>
  
  <p>How do I extract one column from this so my output is something like this:</p>
  
  <pre class="lang-none prettyprint-override"><code>Available   
  Discovery    
  NonDebugCF01 
  NonDebugCF01_BACKUP 
  Software     
  Template     
  breakresetafterfaildelCF01 
  breakresetafterfaildelCF01_BACKUP 
  rootvol      
  vol         
  </code></pre>
  
  <p>The code to run the command and print the output is this:</p>
  
  <pre><code>def get_volumes(usrname, ip):
  
      raw_output = ru.run('volume show', user=usrname, host=ip, set_e=False) //logs onto netapp and runs command
  
      print raw_output
  </code></pre>
  
  <p>When I run <code>print type(raw_output)</code> it says it's unicode.
  Any help would be much appreciated.</p>
