title: numpy reverse multidimensional array
body: <p>What is the simplest way in numpy to reverse the most inner values of an array like this:</p>
  
  <pre><code>array([[[1, 1, 1, 2],
      [2, 2, 2, 3],
      [3, 3, 3, 4]],
  
     [[1, 1, 1, 2],
      [2, 2, 2, 3],
      [3, 3, 3, 4]]])
  </code></pre>
  
  <p>so that I get the following result:</p>
  
  <pre><code>array([[[2, 1, 1, 1],
      [3, 2, 2, 2],
      [4, 3, 3, 3]],
  
     [[2, 1, 1, 1],
      [3, 2, 2, 2],
      [4, 3, 3, 3]]])
  </code></pre>
  
  <p>Thank you very much!</p>
