title: How can I combine dictionaries with the same keys?
body: <p>I have a list of dictionaries like so:</p>
  
  <pre><code>dicts = [
      {'key_a': valuex1,
       'key_b': valuex2,
       'key_c': valuex3},
  
      {'key_a': valuey1,
       'key_b': valuey2,
       'key_c': valuey3},
  
      {'key_a': valuez1,
       'key_b': valuez2,
       'key_c': valuez3}
  ]
  </code></pre>
  
  <p>I would like to take these and construct a big dictionary like so:</p>
  
  <pre><code>big_dict = {
      'key_a': [valuex1, valuey1, valuez1],
      'key_b': [valuex2, valuey2, valuez2],
      'key_c': [valuex3, valuey3, valuez3]
  }
  </code></pre>
  
  <p>Is there any elegant "<a href="http://docs.python.org/library/functions.html#zip" rel="nofollow noreferrer">zip</a>"-like way for me to do this? </p>
  
  <p>All the keys are always going to be identical.</p>
