title: Why doesn`t list[:][0] get me the first row of the list?
body: <p>For the following:</p>
  
  <pre><code>list=[[2, 3, 5], [7, 8, 9]]
  </code></pre>
  
  <p>Why does <code>[list[0][0], list[1][0]]</code> represent the first row ([2, 7]), but the command <code>list[:][0]</code> or <code>list[0:2][0]</code> returns the first column ([2, 3, 5])?</p>
  
  <p>The way I see it <code>list[:][0]</code> should get all the possible values for the first parameter (that is 0 and 1) and 0 for the second, meaning it would return the first row. Instead what it does is return the first column and I can't understand why.</p>
