title: Why should I use operator.itemgetter(x) instead of [x]?
body: <p>There is a more general question here: <a href="https://stackoverflow.com/questions/467920/in-what-situation-should-the-built-in-operator-module-be-used-in-python">In what situation should the built-in <code>operator</code> module be used in python?</a></p>
  
  <p>The top answer claims that <code>operator.itemgetter(x)</code> is "neater" than, presumably, than <code>lambda a: a[x]</code>. I feel the opposite is true.</p>
  
  <p>Are there any other benefits, like performance? </p>
