以下是一些常见的扑克牌相关算法实现，包括洗牌、发牌和基本游戏逻辑：

1. 扑克牌类定义

python

import random

from enum import Enum

class Suit(Enum):

HEARTS = "♥

DIAMONDS = "♦

CLUBS = "♣

SPADES = "♠

class Rank(Enum):

TWO = 2

THREE = 3

FOUR = 4

FIVE = 5

SIX = 6

SEVEN = 7

EIGHT = 8

NINE = 9

TEN = 10

JACK = 11

QUEEN = 12

KING = 13

ACE = 14

class Card:

def __init__(self, suit, rank):

self.suit = suit

self.rank = rank

def __str__(self):

rank_str =

if self.rank.value

rank_str = str(self.rank.value)

else:

rank_str = {11: 'J', 12: 'Q', 13: 'K', 14: 'A'}[self.rank.value]

return f"{rank_str}{self.suit.value}

def __repr__(self):

return self.__str__

2. 扑克牌组类

python

class Deck:

def __init__(self):

self.cards = []

self.reset

def reset(self):

重置牌组为完整的一副牌

self.cards = [Card(suit, rank) for suit in Suit for rank in Rank]

def shuffle(self):

洗牌算法

n = len(self.cards)

for i in range(n-1, 0, -1):

j = random.randint(0, i)

self.cards[i], self.cards[j] = self.cards[j], self.cards[i]

def deal(self, num_cards=1):

发指定数量的牌

if num_cards > len(self.cards):

raise ValueError("牌不够了！")

dealt_cards = self.cards[:num_cards]

self.cards = self.cards[num_cards:]

return dealt_cards

def __len__(self):

return len(self.cards)

def __str__(self):

return f"牌组剩余 {len(self)} 张牌: {self.cards}

3. 德州扑克手牌评估

python

class PokerHandEvaluator:

@staticmethod

def evaluate_hand(cards):

评估手牌强度

返回：(手牌类型, 主要比较值)

手牌类型从高到低：

皇家同花顺 > 同花顺 > 四条 > 满堂红 > 同花 > 顺子 > 三条 > 两对 > 一对 > 高牌

if len(cards)

raise ValueError("至少需要5张牌进行评估")

# 按花色和点数分组

suits = {}

ranks = {}

for card in cards:

suits.setdefault(card.suit, []).append(card)

ranks.setdefault(card.rank.value, []).append(card)

sorted_ranks = sorted([card.rank.value for card in cards], reverse=True)

# 检查同花

flush = False

flush_cards = None

for suit_cards in suits.values:

if len(suit_cards) >= 5:

flush = True

flush_cards = sorted([card.rank.value for card in suit_cards], reverse=True)[:5]

# 检查顺子

straight = False

straight_high = None

unique_sorted = sorted(set(sorted_ranks), reverse=True)

for i in range(len(unique_sorted)

if unique_sorted[i]

straight = True

straight_high = unique_sorted[i]

break

# 特殊情况：A-2-3-4-5顺子

if set([14, 2, 3, 4, 5]).issubset(set(sorted_ranks)):

straight = True

straight_high = 5

# 检查各种组合

pairs = []

three_of_a_kind = False

four_of_a_kind = False

for rank_value, rank_cards in ranks.items:

count = len(rank_cards)

if count == 4:

four_of_a_kind = True

four_rank = rank_value

elif count == 3:

three_of_a_kind = True

three_rank = rank_value

elif count == 2:

pairs.append(rank_value)

pairs.sort(reverse=True)

# 确定手牌类型

if flush and straight:

if straight_high == 14: # A-high straight flush

return ("皇家同花顺", [14])

return ("同花顺", [straight_high])

if four_of_a_kind:

kicker = max(r for r in sorted_ranks if r != four_rank)

return ("四条", [four_rank, kicker])

if three_of_a_kind and len(pairs) >= 1:

return ("满堂红", [three_rank, max(pairs)])

if flush:

return ("同花", flush_cards[:5])

if straight:

return ("顺子", [straight_high])

if three_of_a_kind:

kickers = sorted([r for r in sorted_ranks if r != three_rank], reverse=True)[:2]

return ("三条", [three_rank] + kickers)

if len(pairs) >= 2:

high_pair, low_pair = pairs[0], pairs[1]

kicker = max(r for r in sorted_ranks if r not in [high_pair, low_pair])

_pair])

return ("两对", [high_pair, low_pair, kicker])

if len(pairs) == 1:

kickers = sorted([r for r in sorted_ranks if r != pairs[0]], reverse=True)[:3]

return ("一对", [pairs[0]] + kickers)

return ("高牌", sorted_ranks[:5])

@staticmethod

def compare_hands(hand1, hand2):

比较两手牌的大小

type_order = {

高牌": 0, "一对": 1, "两对": 2, "三条": 3,

顺子": 4, "同花": 5, "满堂红": 6,

四条": 7, "同花顺": 8, "皇家同花顺": 9

type1, values1 = hand1

type2, values2 = hand2

if type_order[type1] > type_order[type2]:

return 1

elif type_order[type1]

return -1

else:

# 相同类型，比较值

for v1, v2 in zip(values1, values2):

if v1 > v2:

return 1

elif v1

return -1

return 0

4. 使用示例

python

def main:

# 创建并洗牌

deck = Deck

print("初始牌组:")

print(deck)

deck.shuffle

print("\

洗牌后:")

print(deck)

# 发牌给玩家

players = [[] for _ in range(4)]

for _ in range(2): # 每人发两张手牌

for i in range(4):

players[i].extend(deck.deal)

print("\

玩家手牌:")

for i, hand in enumerate(players):

print(f"玩家 {i+1}: {hand}")

# 发公共牌

community_cards = deck.deal(5)

print(f"\

公共牌: {community_cards}")

# 评估每个玩家的最佳五张牌

print("\

玩家最佳手牌评估:")

player_hands = []

for i, hand in enumerate(players):

all_cards = hand + community_cards

best_hand_type, best_values = PokerHandEvaluator.evaluate_hand(all_cards)

player_hands.append((best_hand_type, best_values))

print(f"玩家 {i+1}: {best_hand_type} {best_values}")

# 找出获胜者

winner = 0

for i in range(1, len(player_hands)):

if pare_hands(player_hands[i], player_hands[winner]) > 0:

winner = i

print(f"\

获胜者是玩家 {winner+1}!")

if __name__ == "__main__":

main

5. 其他实用函数

python

def simulate_probability(num_simulations=10000):

模拟特定手牌获胜的概率

wins = 0

for _ in range(num_simulations):

deck = Deck

deck.shuffle

# 假设玩家1有特定的手牌

player1_hand = [

Card(Suit.HEARTS, Rank.ACE),

Card(Suit.HEARTS, Rank.KING)

# 从牌组中移除这些牌

deck.cards = [card for card in deck.cards if card not in player1_hand]

# 发牌给其他玩家

other_players = [[] for _ in range(3)]

for _ in range(2):

for i in range(3):

other_players[i].extend(deck.deal)

# 发公共牌

community_cards = deck.deal(5)

# 评估所有玩家的手牌

player1_all = player1_hand + community_cards

player1_eval = PokerHandEvaluator.evaluate_hand(player1_all)

is_winner = True

for hand in other_players:

player_all = hand + community_cards

player_eval = PokerHandEvaluator.evaluate_hand(player_all)

if pare_hands(player_eval, player1_eval) > 0:

is_winner = False

break

if is_winner:

wins += 1

probability = wins / num_simulations

print(f"在 {num_simulations} 次模拟中，该手牌获胜概率为: {probability:.2%}")

return probability

这些算法涵盖了扑克牌游戏中的核心功能，包括洗牌、发牌和手牌评估。您可以根据需要扩展这些基础功能来实现更复杂的扑克游戏逻辑。
