Replying to the question in subject, I think it would be better in collections as a class. Having it just as a function doesn't buy much, because one can do the same with three lines and a defaultdict. However, if this is a class it can support adding new elements, merge the groupeddicts, etc.
defaultdicts support adding new elements, and they have an update method same as regular dicts :-)
