title: Pandas memoization
body: <p>I have lengthy computations which I repeat many times. Therefore, I would like to use memoization (packages such as <a href="http://packages.python.org/Jug">jug</a> and <a href="http://packages.python.org/joblib/memory.html">joblib</a>), in concert with <a href="http://pandas.pydata.org">Pandas</a>. The problem is whether the package would memoize well Pandas DataFrames as method arguments.</p>
  
  <p>Has anyone tried it? Is there any other recommended package/way to do this?</p>
