title: Building a list of dictionary values, sorted by key
body: <p>I have a python dictionary that looks something like this:</p>
  
  <pre><code>attributes = {
      'size': ['s','m','l'],
      'color': ['black', 'orange'],
  }
  </code></pre>
  
  <p>I want to get a list of values. If I use <code>values()</code>, I get this:</p>
  
  <pre><code>&gt;&gt;&gt; attributes.values()
  [['black', 'orange'], ['s', 'm', 'l']]
  </code></pre>
  
  <p>However, I want the resulting list of lists to be sorted by the dictionary key in reverse order -- ie, size and then color, not color and then size. I want this:</p>
  
  <pre><code>[['s', 'm', 'l'], ['black', 'orange']]
  </code></pre>
  
  <p>I do not necesarilly know what the dictionary keys will be beforehand, but I do always know if I want them in alphabetical or reverse alphabetical order.</p>
  
  <p>Is there some pythonic way to do this?</p>
  
  <p>The only thing I can think of seems... not very python-like:</p>
  
  <pre><code>keys = sorted(attributes.keys(), reverse=True)
  result = []
  for key in keys:
      result.append(attributes[key])
  </code></pre>
  
  <p>It's hard to go from <code>attributes.values()</code> to all of that just to sort the list!</p>
