title: Python inserting a row in a 2Darray
body: <p>I have an 5x17511 2D array <em>(name = 'da'</em>) which made by a <code>pandas.read_csv(...)</code></p>
  
  <p>I also added one column for indexing like this: <code>da.index = pd.date_range(...)</code></p>
  
  <p>So my 2D array has 6x17511 size now.</p>
  
  <p>I'd like to insert/append one more row to this 2D array, how to do this?</p>
  
  <p>I already tried with: <code>np.insert(da,1,np.array((1,2,3,4,5,6)), 0)</code> but it says:</p>
  
  <blockquote>
    <p>ValueError: Shape of passed values is (6, 17512), indices imply (6,
    17511)</p>
  </blockquote>
  
  <p>Thanks in advance!</p>
