<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 577452 by <a href="/recipes/users/4016391/">Daniel Miller</a> (<a href="/recipes/tags/cache/">cache</a>, <a href="/recipes/tags/functools/">functools</a>, <a href="/recipes/tags/memoize/">memoize</a>, <a href="/recipes/tags/partial/">partial</a>). </p> <p>A simple result-caching decorator for instance methods. NOTE: does not work with plain old non-instance-method functions. The cache is stored on the instance to prevent memory leaks caused by long-term caching beyond the life of the instance (almost all other recipes I found suffer from this problem when used with instance methods).</p>
