title: Python- if statement evaluation pattern
body: <p>what the heck is the if statement doing?</p>
  
  <pre><code>&gt;&gt;&gt; list = ['a', 'b', 'c', 'd', 'e', 'f']
  &gt;&gt;&gt; for i in xrange(len(list)):
  ...   if i / 2:
  ...     del(list[0])
  </code></pre>
  
  <p>and this will result in ['e', 'f']</p>
  
  <p>I dont know that the if is doing.</p>
