I need to have a dictionary of dictionaries of numbers, and I would like the
dictionaries to be defaultdicts, because it makes the code much nicer
(I want to be able to do: d['foo']['bar']+=1 ).
So naturally, I used:
d = defaultdict(lambda :defaultdict(int))
It works great, but now I can not pickle it.
I could ofcourse used a real function and not a lambda, but this would make
things (a) somewhat slower and (b) a bit ugly.
Is there another way of achieving the same behaviour, that allow for
