iterating over a combinatorial class
It is somewhat annoying that
next don't do what you think with combinatorial classes. Is there any more Pythonic (e.g. list comprehension) way to do the following?
prof = [1,3,2,0,0,3] L =  P = Permutations(3) Q = P.__iter__() for j in range(P.cardinality()): tp = Q.next() for i in range(prof[j]): L.append(tp)
Part of the issue is that I would really rather not use
Q, since it is "used up" when I'm done. I really want something that is succinct, but I just could not find a way to do it.
