title: How to slice middle element from list
body: <p>Rather simple question. Say I have a list like:</p>
  
  <pre><code>a = [3, 4, 54, 8, 96, 2]
  </code></pre>
  
  <p>Can I use slicing to leave out an element around the middle of the list to produce something like this?</p>
  
  <pre><code>a[some_slicing]
  [3, 4, 8, 96, 2]
  </code></pre>
  
  <p>were the element <code>54</code> was left out. I would've guessed this would do the trick:</p>
  
  <pre><code>a[:2:]
  </code></pre>
  
  <p>but the result is not what I expected:</p>
  
  <pre><code>[3, 4]
  </code></pre>
