連休明けまでに書けばいいやと思っていた講義用のシミュレータが、２時間後の実験に必要であることが判明して、３０分で書く。
import random
deck = range(2,10)
deck += [10] * 4
deck += [11]
deck *= 4
result = { j:{i:0 for i in range(17,23)} for j in range(2,12) }
print("Deck check")
print(deck)
for c in range(1000):
random.shuffle(deck)
hand = deck[-1]
if deck[-1] == 11:
hasa = 1
else:
hasa = 0
for draw in deck:
hand = hand + draw
if draw == 11:
hasa += 1
if hand > 21 and hasa > 0:
hand = hand - 10
hasa -= 1
if hand >= 17:
break
if hand>21:
hand = 22
result[deck[-1]][hand] += 1
print("Simulation Result")
for k, r in result.iteritems():
print("%d : %s" % (k, r) )
