title: Concatenate two lists side by side
body: <p>I am looking for the shortest way of doing the following (one line solution)</p>
  
  <pre><code>a = ["a", "b", "c"]
  b = ["w", "e", "r"]
  </code></pre>
  
  <p>I want the following output:</p>
  
  <pre><code>q = ["a w", "b e", "c r"]
  </code></pre>
  
  <p>Of course this can be achieved by applying a for loop. But I am wondering if there is a smart solution to this?</p>
