title: Creating Arrays in numpy using zeros
body: <p>I've been trying to create a 6 by 6 array in python using the numpy module with all elements set as 0.0:</p>
  
  <pre><code>import numpy as np
  RawScores = np.zeros((6,6), dtype=np.float)
  print RawScores
  </code></pre>
  
  <p>This outputs:</p>
  
  <pre><code>[[ 0.  0.  0.  0.  0.  0.]
   [ 0.  0.  0.  0.  0.  0.]
   [ 0.  0.  0.  0.  0.  0.]
   [ 0.  0.  0.  0.  0.  0.]
   [ 0.  0.  0.  0.  0.  0.]
   [ 0.  0.  0.  0.  0.  0.]]
  </code></pre>
  
  <p>Why are there no commas? Is it still an array without them?</p>
