<p style="color: grey"> Python recipe 577658 by <a href="/recipes/users/4177684/">Ethan Furman</a> (<a href="/recipes/tags/class_decorator/">class_decorator</a>, <a href="/recipes/tags/composition/">composition</a>, <a href="/recipes/tags/inheritance/">inheritance</a>, <a href="/recipes/tags/multiple_inheritance/">multiple_inheritance</a>). </p> <p>MI can be difficult and confusing, and if the base classes don't cooperate -- well, cooperative MI won't work.</p> <p>One way around this is to use composition instead. This class decorator will combine the source classes with the target class, ensuring that no duplications occur (raises a TypeError if there are any).</p>
