title: concurrently iterating through even and odd items of list
body: <p>I have a list of items (which are HTML table rows, extracted with Beautiful Soup) and I need to iterate over the list and get even and odd elements (I mean index) for each loop run. 
  My code looks like this:</p>
  
  <pre><code>for top, bottom in izip(table[::2], table[1::2]):
      #do something with top
      #do something else with bottom
  </code></pre>
  
  <p>How to make this code less ugly? Or maybe is it good way to do this?</p>
  
  <p>EDIT: </p>
  
  <pre><code>table[1::2], table[::2]  =&gt; table[::2], table[1::2]
  </code></pre>
