<p style="color: grey"> Python recipe 577190 by <a href="/recipes/users/4173653/">Paul G</a> (<a href="/recipes/tags/binary/">binary</a>, <a href="/recipes/tags/multiply/">multiply</a>, <a href="/recipes/tags/product/">product</a>, <a href="/recipes/tags/set/">set</a>). </p> <p>This recipe provides a subclass of set which implements __mul__ and __pow__ to support the computation of set products. When multiplying two sets together, a new set is produced with elements which are the inter-set pairs.</p>
