<p style="color: grey"> Python recipe 577992 by <a href="/recipes/users/4180313/">Peter Donis</a> (<a href="/recipes/tags/decorators/">decorators</a>, <a href="/recipes/tags/generators/">generators</a>, <a href="/recipes/tags/memoization/">memoization</a>, <a href="/recipes/tags/memoize/">memoize</a>). Revision 2. </p> <p>A wrapper class for generators that "memoizes" them, so that even if the generator is realized multiple times, each term only gets computed once (after that the result is simply returned from a cache).</p>

<p style="color: grey"> Python recipe 576429 by <a href="/recipes/users/4166509/">Michael Pust</a> (<a href="/recipes/tags/generators/">generators</a>, <a href="/recipes/tags/lazy/">lazy</a>, <a href="/recipes/tags/memoization/">memoization</a>). </p> <p>Dan Spitz submitted a recipe ( <a href="http://code.activestate.com/recipes/576410/">576410</a> ) for recursively defined lazy lists backed by a generator. Only catch was that it was written for python 3k. But there is nothing intrinsic in 3k that prevents you from having the same functionality in python 2.5, so I am supplying the backport here.</p>
