title: I want itertools to return a list of lists
body: <p>I'm using <code>itertools</code> to generate all possible permutations of a list. I would like it to return a list of lists, but this is not what I'm getting.</p>
  
  <p>For example</p>
  
  <pre><code>import itertools
  print list(itertools.permutations([1, 2]))
  </code></pre>
  
  <p>returns</p>
  
  <pre><code>&gt;&gt;&gt; [(1, 2), (2, 1)]
  </code></pre>
  
  <p>But I was expecting</p>
  
  <pre><code>&gt;&gt;&gt; [[1, 2], [2, 1]]
  </code></pre>
  
  <p>Is it possible?</p>
