Python built in types are enough for this problem IMO. You can use sets of
tuples to specify ticket and drawings and then just do set intersection.
Say the drawing is set([(5, 'wb'), (1, 'wb'), (45, 'wb'), (23, 'wb'), (27,
'wb')]) (keeping black ball out). The you can create a score function:
Side note: I might used a namedtuple to have drawing.whites, drawing.black.
def score(ticket_whites, ticket_black, drawing_whites, drawing_black):
num_whites = ticket_whites & drawing_whites
black_matching = ticket_black == drawing_black
return {
(2, True) : 1,
(3, False) : 2,
(3, True) : 3,
(4, False) : 4,
(4, True) : 5,
(5, False) : 6,
(5, True) : 10
}[(num_whites, black_matching)]
