title: One liner to determine if dictionary values are all empty lists or not
body: <p>I have a dict as follows:</p>
  
  <pre><code>someDict = {'a':[], 'b':[]}
  </code></pre>
  
  <p>I want to determine if this dictionary has any values which are not empty lists.  If so, I want to return True.  If not, I want to return False.  Any way to make this a one liner?</p>
