title: Convert list into a dictionary
body: <pre><code>l = ["a", "b", "c", "d", "e"]
  </code></pre>
  
  <p>I want to convert this list to a dictionary like:</p>
  
  <pre><code>d = {"a": "b", "c": "d", "e": ""}
  </code></pre>
  
  <p>So basically, the evens will be keys whereas the odds will be values. I know that I can do it in a "non-pythonic" way such as a for loop with if statements but I believe that there should be a more "pythonic" way to accomplish this. So, I appreciate any help :) </p>
