title: Zip with list output instead of tuple
body: <p>What is the fastest and most elegant way of doing list of lists from two lists?</p>
  
  <p>I have</p>
  
  <pre><code>In [1]: a=[1,2,3,4,5,6]
  
  In [2]: b=[7,8,9,10,11,12]
  
  In [3]: zip(a,b)
  Out[3]: [(1, 7), (2, 8), (3, 9), (4, 10), (5, 11), (6, 12)]
  </code></pre>
  
  <p>And I'd like to have</p>
  
  <pre><code>In [3]: some_method(a,b)
  Out[3]: [[1, 7], [2, 8], [3, 9], [4, 10], [5, 11], [6, 12]]
  </code></pre>
  
  <p>I was thinking about using map instead of zip, but I don't know if there is some standard library method to put as a first argument.</p>
  
  <p>I can def my own function for this, and use map, my question is if there is already implemented something. <strong>No</strong> is also an answer.</p>
