I was really inspired by this discussion thread! :-) After much tinkering, I think I have a simpler solution. Just make the inverse mapping accessible via an attribute, -AND- bind the inverse of -THAT- mapping back to the original. The result is a python dict with NO NEW METHODS except this inverse-mapping attribute. I have posted it on code.activestate.com as <a href="http://code.activestate.com/recipes/576968/";>Recipe 576968: Flipdict -- python dict that also maintains a one-to-one inverse mapping</a>
