<p style="color: grey"> Python recipe 577283 by <a href="/recipes/users/4174299/">Pietro Berkes</a> (<a href="/recipes/tags/decorator/">decorator</a>, <a href="/recipes/tags/function/">function</a>, <a href="/recipes/tags/inner/">inner</a>, <a href="/recipes/tags/local/">local</a>, <a href="/recipes/tags/scope/">scope</a>, <a href="/recipes/tags/variables/">variables</a>). Revision 2. </p> <p>Decorator to expose the local variables defined in the inner scope of a function. At the exit of the decorated function (regular exit or exceptions), the local dictionary is copied to a read-only property, <code>locals</code>.</p> <p>The main implementation is based on injecting bytecode into the original function, and requires the lightweight module <code>byteplay</code> (available <a href="http://code.google.com/p/byteplay/">here</a>). See below for an alternative implementation that only uses the standard library.</p>
