斗地主引擎

Build Status Supported Python versions PyPI Version

通过枚举37种细分牌型,制作一个花色无关、顺序无关的字典,字典规模大小是34152,能够在O(1)时间内判断出牌是否有效、比较大小。

基于组合数学,设计思路见详细文档

Keep in mind

  • 扑克出牌是54张牌的组合,牌型和排列顺序无关
  • 在斗地主游戏中,牌型及大小和花色无关
  • 两个王不算对子
  • 同一手牌,可以作为不同牌型,如3-3-3-3-2-2-2-23-3-3-4-4-4-5-5-5-6-6-6

扑克的表示

15种点数

'3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A', '2', 'BJ', 'CJ'
  • BJ: Black Joker 小王/花/鬼
  • CJ: Colored Joker 大王/花/鬼

4种花色

's': spades   黑桃 ♠
'h': hearts   红心 ❤
'd': diamonds 方块 ♦
'c': clubs    梅花 ♣

举例

'2c': 单张[ 2  ]
'2h-2s-2d-2c-BJ-CJ': 四个2带两王[ 2  ] , [ 2  ] , [ 2  ] , [ 2  ] , [ BJ  ] , [ CJ  ]
'3c-4d-5h-6s-7s-8h-9h': 顺子[ 3  ] , [ 4  ] , [ 5  ] , [ 6  ] , [ 7  ] , [ 8  ] , [ 9  ]

检查牌型

>>> from doudizhu import Card, check_card_type
>>> test_chain = Card.card_ints_from_string('3c-4d-5h-6s-7s-8h')
>>> test_four_two = Card.card_ints_from_string('2c-2d-2h-2s-BJ-CJ')
>>>
>>> check_card_type(test_four_two)
(True, [('four_two_solo', 13)])
>>> check_card_type(test_chain)
(True, [('solo_chain_6', 0)])
>>> check_card_type(test_chain[:4])
(False, ValueError('invalid card type',))

比较大小

>>> from doudizhu import Card, cards_greater
>>> chain = Card.card_ints_from_string('3c-4d-5h-6s-7s-8h-9h')
>>> bomb = Card.card_ints_from_string('8h-8s-8d-8c')
>>> rocket = Card.card_ints_from_string('BJ-CJ')
>>>
>>> cards_greater(chain, chain)
(False, 'solo_chain_7')
>>> cards_greater(chain[:6], chain[1:7])
(False, 'solo_chain_6')
>>>
>>> cards_greater(chain[1:7], chain[:6])
(True, 'solo_chain_6')
>>> cards_greater(bomb, chain)
(True, 'bomb')
>>> cards_greater(rocket, bomb)
(True, 'rocket')
