Now that it is solved it's fair game for anyone :-) I have no
information whether this is homework for you or not, and posting in a
public newsgroup defeats cheating.
for c in coins :
n, units = divmod(units, c)
if n: yield c, n
if not units: raise StopIteration
raise ValueError, 'no change!'
coins = [200,100,50,20,10,5,2,1]
for i in range(501):
D = dict(split(i,coins))
nc = sum(D.values())
check = sum([c*n for c,n in D.items()])
print "%3i: %i coins:" %(i,nc) , D
assert check == i
