title: Python combine two for loops
body: <p>Currently I would do:</p>
  
  <pre><code>for x in [1,2,3]:
      for y in [1,2,3]:
          print x,y
  </code></pre>
  
  <p>Is there way of doing something like below,</p>
  
  <pre><code>for x,y in ([1,2,3],[1,2,3]):
      print x,y
  </code></pre>
  
  <p>Would like to shorten this kind of loop and this throws the "too many to unpack" exception.</p>
