title: slice numpy array by column except for 1 row
body: <p>How can you slice a numpy array by column, and exclude a particular row?</p>
  
  <p>Imagine you have a numpy array where the first column serves as an index as to a 'player', and the next columns are the players scores at different games. How can you return the scores for a game, whilst excluding one player.</p>
  
  <p>For example:</p>
  
  <pre><code>[0  0  0  0
   1  2  1  1 
   2 -6  0  2
   3  4  1  3]
  </code></pre>
  
  <p>If you want to return the first score (column 1), you would do:</p>
  
  <pre><code>&gt;&gt;score[:,1]
  [0,2,-6,4]
  </code></pre>
  
  <p>But how can you exclude a player/row? 
  If that player/row 3, how do you get:</p>
  
  <pre><code>[0,2,-6]
  </code></pre>
  
  <p>Or, if that player/row 1, how do you get:</p>
  
  <pre><code>[0,-6, 4]
  </code></pre>
