Use xrange instead of range. If you want to do it with no variables,
hmmm:
from itertools import islice, starmap, repeat
import random
possible_notes = range(12)
length = 9
print list(islice(starmap(random.choice, repeat((possible_notes,))), length))

[10, 0, 6, 7, 8, 1, 9, 6, 11]
Maybe you're sorry you asked ;)
