<p style="color: grey"> Python recipe 578918 by <a href="/recipes/users/4172944/">Steven D'Aprano</a> (<a href="/recipes/tags/shortcuts/">shortcuts</a>). </p> <p>Yet another look at Raymond Hettinger's excellent "namedtuple" factory. Unlike Raymond's version, this one minimizes the use of exec. In the original, the entire inner class is dynamically generated then exec'ed, leading to the bulk of the code being inside a giant string template. This version uses a regular inner class for everything except the __new__ method.</p>

<p style="color: grey"> Python recipe 578865 by <a href="/recipes/users/4189822/">He Gu</a> (<a href="/recipes/tags/shortcuts/">shortcuts</a>). </p> <p>Sometimes you want to have a list comprehension refer to itself, but you can't because it isn't bound to a name until after it is fully constructed. However, the interpreter creates a secret name that only exists while the list is being built. That name is (usually) "_[1]", and it refers to the bound method "append" of the list. This is our back door to get at the list object itself.</p>

Revision 3. </p> <p>Python does not support assignment in if and while statements such as "if (x=func()):". This is an attempt to bring similar functionality to python by injecting bytecode to all functions and methods in a module. This recipe is inspired from recipes <a href="http://code.activestate.com/recipes/66061">66061</a>, <a href="http://code.activestate.com/recipes/202234-assignment-in-expression">202234</a> and <a href="http://code.activestate.com/recipes/277940-decorator-for-bindingconstants-at-compile-time">277940</a>.</p>

It can be easily extended other time zones and other operating systems.</p>

<p style="color: grey"> Python recipe 498245 by <a href="/recipes/users/178123/">Raymond Hettinger</a> (<a href="/recipes/tags/shortcuts/">shortcuts</a>). Revision 6. </p> <p>One-line decorator call adds caching to functions with hashable arguments and no keyword arguments. When the maximum size is reached, the least recently used entry or least frequently used entry is discarded -- appropriate for long-running processes which cannot allow caches to grow without bound. Includes built-in performance instrumentation.</p>
