title: Is there a way to output the numbers only from a python list?
body: <p>Simple Question:</p>
  
  <pre><code>list_1 = [ 'asdada', 1, 123131.131, 'blaa adaraerada', 0.000001, 34.12451235265, 'stackoverflow is awesome' ]
  </code></pre>
  
  <p>I want to create a <code>list_2</code> such that it only contains the numbers:</p>
  
  <pre><code>list_2 = [ 1, 123131.131, 0.000001, 34.12451235265 ]
  </code></pre>
  
  <p>Is there simplistic way of doing this, or do I have to resort to checking the variable type of each list item and only output the numerical ones?</p>
