title: Changed Nested list items to integer format
body: <p>How do I filter or remove the <code>.0</code> at the end of my numbers? I tried converting them to integers but lists don't allow that. Is regex my best option? I don't need to do any maths with the numbers. I just need to remove the <code>.0</code> at the end.
  all help welcome.</p>
  
  <pre><code>Nums  = [['17001.0', '17001.0'], ['17001.0', '11001.0'], ['17001.0', '18001.0'], ['17001.0', '19001.0'],
       ['14001.0', '12001.0'], ['19001.0', '18001.0'], ['19001.0', '16001.0'], ['15001.0'], ['16001.0'],
       ['18001.0'], ['19001.0'], ['18001.0'], ['22.0'], ['22.0'], ['22.0'], ['19001.0']]
  </code></pre>
