<p style="color: grey"> Python recipe 577628 by <a href="/recipes/users/4177507/">Nabil Stendardo</a> (<a href="/recipes/tags/class/">class</a>, <a href="/recipes/tags/modification/">modification</a>, <a href="/recipes/tags/monkeypatching/">monkeypatching</a>, <a href="/recipes/tags/open/">open</a>). </p> <p>However considered bad programming, Ruby/JavaScript-like open classes (i.e. classes which can be modified at runtime) actually can be a programming pattern when developing plug-in architectures. And, guess what, Python has that functionality too. This code allows to add attributes (typically methods) to classes, even when already instantiated.</p>
