title: How to populate dictionary values as list with the same keys
body: <p>I have a list of dictionary. I need to grow dictionary values under each keys as list in a loop (or any other way).</p>
  
  <pre><code>dl= [{'A':1, 'B':2}, {'A':3, 'B':4}, {'A':5, 'B':6}]
  for d in dl:
      ?????
  </code></pre>
  
  <p>What I need is a dictionary like this:</p>
  
  <pre><code>{'A':[1,3,5], 'B': [2,4,6]}
  </code></pre>
  
  <p>I need a way without using pandas dataframe. Thanks a lot.</p>
