title: Extracting Pylint Score
body: <p>Does anyone know how to extract <em>only</em> the pylint score for a repository?</p>
  
  <p>So, assuming pylint produces the following output:</p>
  
  <pre><code>Global evaluation
  -----------------
  Your code has been rated at 6.67/10 (previous run: 6.67/10, +0.00)
  </code></pre>
  
  <p>I would like it to return a value of 6.67.</p>
  
  <p>Thanks,</p>
  
  <p>Seán</p>
