title: How do I flatten a list of lists/nested lists?
body: <p>I have python code like this:</p>
  
  <pre><code>newlist =[[52, None, None], [129, None, None], [56, None, None], [111, None, None],  
            [22, None, None], [33, None, None], [28, None, None], [52, None, None],  
            [52, None, None], [52, None, None], [129, None, None], [56, None, None],  
            [111, None, None], [22, None, None], [33, None, None], [28, None, None]]
  </code></pre>
  
  <p>I want the <code>newlist</code> like:</p>
  
  <pre><code>newlist =[52, None, None,129, None, None,56, None, None,111, None, None,22, 
            None, None,33, None, None,28, None, None,52, None, None,52, None,  
            None,52, None, None,129, None, None,56, None, None, 111, None,  
            None,22, None, None,33, None, None,28, None, None]
  </code></pre>
  
  <p>Is there any way to work around ?</p>
