title: Error while merging split part of numpy array
body: <pre><code>test = [(0,1,2),(9,0,1),(0,1,3),(0,1,8)]
  test=np.array(test)
  test = np.array_split(test, 4)
  t_0 = test[:0]
  t_1 = test[0]
  new_test= t_0+test[1:]
  print(new_test)  
  </code></pre>
  
  <p>It is giving me following answer : <code>[array([[9, 0, 1]]), array([[0, 1, 3]]), array([[0, 1, 8]])]</code></p>
  
  <p>Whereas I am aiming for <code>[(9,0,1),(0,1,3),(0,1,8)]</code> if I select the first set from test.</p>
