title: Python Deque appendleft with list
body: <p>I am currently creating my <code>deque</code> object using the following,</p>
  
  <pre><code>self.CommandList = deque((['S', False, 60],['c'],['g16'],['i50'],['r30', True],['u320'],['o5000'],['b1'],['B4500'],['W1'],['l5154'],['!10'],['p2', True, 10],['e1'],['K20'],['U0'],['Y0']))
  </code></pre>
  
  <p>But I wish to add a similar list to the queue later but using <code>appendleft</code>, so it can jump ahead of the list. I assumed the following, but had no luck.</p>
  
  <pre><code>NewList = (['S'],['c'],['!10'],['p4'],['o1200'],['i50'],['r30'],['b10'],['d1'],['A', True, 163])
  self.CommandList.appendleft(NewList)
  </code></pre>
  
  <p>Is this even possible with <code>appendleft</code>?</p>
