title: Delimiter of numpy.savetxt
body: <p>I am trying to write a numpy array to a <code>.txt</code> file using <a href="http://docs.scipy.org/doc/numpy/reference/generated/numpy.savetxt.html" rel="nofollow"><code>numpy.savetxt</code></a>.  To the best I can tell, the following code follows the documentation:</p>
  
  <pre><code>z = np.array([1,2,3])
  np.savetxt('testdata.txt',z,delimiter='hi')
  </code></pre>
  
  <p>However, the output file, opened with Notepad, shows</p>
  
  <pre><code>1.000000000000000000e+002.000000000000000000e+003.000000000000000000e+00
  </code></pre>
  
  <p>without the delimiter <code>hi</code> between the values.  Any ideas why this might be?  My goal is to add new lines between each value.</p>
