title: Transforming a 2D array to a list
body: <p>Let's assume I have an 2D array named 'example'</p>
  <pre><code>example = np.array([[14],[34],[234],[17],[80],[4563],[1456],[2345],[3456],[34565]])
  </code></pre>
  <p>What I want to do here is to transform the array to a list that looks like:</p>
  <p>[14, 34, 234, 17, 80, 4563, 1456, 2345, 3456, 34565]</p>
  <p>How can I get the above list from the array?</p>
