title: Find the item with maximum occurrences in a list
body: <p>In Python, I have a list:</p>
  
  <pre><code>L = [1, 2, 45, 55, 5, 4, 4, 4, 4, 4, 4, 5456, 56, 6, 7, 67]  
  </code></pre>
  
  <p>I want to identify the item that occurred the highest number of times. I am able to solve it but I need the fastest way to do so. I know there is a nice Pythonic answer to this.  </p>
