Try using setdefault:
>>> d = {'a':[1,2], 'b':[2,3], 'c':[3]

I searched for an hour and don't see a solution to this (i assume
somewhat common) problem.
I have a very large dictionary of lists:
d = {a:[1,2], b:[2,3], c:[3]}
and i want to reverse the associativity of the integers thusly:
inverse(d) makes {1:[a], 2:[a,b], 3:[b,c]}
my solution expands the
