title: Shape of array python
body: <p>Suppose I create a 2 dimensional array </p>
  
  <pre><code> m = np.random.normal(0, 1, size=(1000, 2))
   q = np.zeros(shape=(1000,1))
   print m[:,0] -q
  </code></pre>
  
  <p>When I take <code>m[:,0].shape</code> I get <code>(1000,)</code> as opposed to <code>(1000,1)</code> which is what I want. How do I coerce <code>m[:,0]</code> to a <code>(1000,1)</code> array?</p>
