<p style="color: grey"> Python recipe 578696 by <a href="/recipes/users/4188267/">-</a> (<a href="/recipes/tags/class_factory/">class_factory</a>, <a href="/recipes/tags/encode/">encode</a>, <a href="/recipes/tags/json/">json</a>, <a href="/recipes/tags/metaclass/">metaclass</a>, <a href="/recipes/tags/metaclasses/">metaclasses</a>). </p> <p>The <em>json.dumps</em> need to be feed with some class (cls =someClass) but what if we want to change the class dynamically? This example can be done by declaring the <em>listOfClasses</em> in class level of course, but the idea is to be changeable. This can be done by the class factory function <em>encoderFacory</em></p>

<p style="color: grey"> Python recipe 576951 by <a href="/recipes/users/4172249/">Ariel Balter</a> (<a href="/recipes/tags/class_factory/">class_factory</a>). Revision 2. </p> <p>I'm a hack programmer -- no formal education. So, I don't know if this is technically a "factory", "abstract factory" or something else.</p> <p>It is a way to generate a class dynamically, perhaps based on run-time data.</p> <p>The point is that you can take a blank class object and dynamically add a constructor, class attributes, and instance methods. In principle, these could be configured dynamically in a program.</p> <p>Since I don't know anything about programming theory, I welcome any criticism/discussion/suggestion. But, please be gentle!</p>
