title: Python iterate over two lists simultaneously
body: <p>Is there a way in python to forloop over two or more lists simultaneously?</p>
  
  <p>Something like</p>
  
  <pre><code>a = [1,2,3]
  b = [4,5,6]
  for x,y in a,b:
      print x,y
  </code></pre>
  
  <p>to output</p>
  
  <pre><code>1 4
  2 5
  3 6
  </code></pre>
  
  <p>I know that I can do it with tuples like</p>
  
  <pre><code>l = [(1,4), (2,5), (3,6)]
  for x,y in l:
      print x,y
  </code></pre>
