title: Merge two arrays vertically to array of tuples using numpy
body: <p>I have two numpy arrays:</p>
  <pre><code>x = np.array([-1, 0, 1, 2])
  y = np.array([-2, -1, 0, 1])
  </code></pre>
  <p>Is there a way to merge these arrays together like tupples:</p>
  <pre><code>array = [(-1, -2), (0, -1), (1, 0), (2, 1)]
  </code></pre>
