title: removing and storing list from dictionary
body: <p>In python, 
  I have a dictionary composed of the following: </p>
  
  <pre><code>[ ['FOXP2_MOUSE', 'AminoAcidSequence1'], ['FOXP2_RAT','AminoAcidSequence2'], ['FOXP2_DOG', 'AminoAcidSequence3'] ].
  </code></pre>
  
  <p>I'm trying to remove the keyed <code>FOXP2_DOG</code> from the dictionary and place it in a new dictionary alone. I've tried different methods: <code>del</code> and <code>.remove</code> to no avail. </p>
