title: How to flatten a "complex" dictionary into a list
body: <p>I have the following dictionary structure:</p>
  
  <pre><code>{'AA': [('No Av', 'Ave', 3.35, 'Max', 0.9, 'Min', -6.8), ('analist disp:', -5.0), u' AA: Jan 11, 2016\t\t\t']}
  </code></pre>
  
  <p>where</p>
  
  <pre><code>u' AA: Jan 11, 2016\t\t\t' 
  </code></pre>
  
  <p>is just a unicode string.</p>
  
  <p>I would like to flatten it into a list like this:</p>
  
  <pre><code>['AA', 'No Av', 'Ave', 3.35, 'Max', 0.9, 'Min', -6.8, 'analist disp:', -5.0, u' AA: Jan 11, 2016\t\t\t']
  </code></pre>
  
  <p>I have tried so many alternatives and nothing works out.</p>
