title: Python/Numpy: Setting values to index ranges
body: <p>Using Numpy, I can create a 5-dimensional array like this:</p>
  
  <pre><code>&gt;&gt;&gt; faces = numpy.zeros((3, 3, 3, 6, 3))
  </code></pre>
  
  <p>I want <code>(all indexes, all indexes, 0, 4)</code> to be set to <code>(1., 1., 1.)</code>.  Is this possible by only using Numpy (no Python loops)?</p>
