<p style="color: grey"> Python recipe 576428 by <a href="/recipes/users/4166478/">nosklo</a> (<a href="/recipes/tags/list/">list</a>, <a href="/recipes/tags/slices/">slices</a>, <a href="/recipes/tags/subclass/">subclass</a>, <a href="/recipes/tags/__getitem__/">__getitem__</a>). Revision 2. </p> <p>As subclassing list has a problem when using __getitem__, __delitem__ and __setitem__ methods with slices (they don't get called because parent implements __getslice__, __delslice__ and __setslice__ respectively), I've coded this UserList class that is a subclass of list, but overwrites these methods. By subclassing this class, you can overwrite __getitem__ and it will be called correctly for slices.</p>
