You should try these things before assuming they don't
work!
There is no problem at all having a dictionary of lists.
This
d_of_l = { 'a': [0,1,2], 'b':[3,4,5]}
is perfectly legal. Only the *keys* of a dictionary must
be hashable, any objects can be *values*.
If you *do* want to make a list into a tuple, BTW (e.g
if you decide you do want to use them as keys), then you
just need this:
tuple(mylist)
