### Python 实现黑杰克（21点）游戏 以下是用 Python 编写的一个简单版的黑杰克（21点）游戏代码示例。此代码实现了基本的游戏逻辑，包括发牌、计算总分以及判断胜负等功能。 ```python import random def deal_card(): """返回一张随机卡牌""" cards = ['A', 'K', 'Q', 'J', 10, 9, 8, 7, 6, 5, 4, 3, 2] card = random.choice(cards) return card def calculate_score(hand): """计算手牌分数""" score = 0 ace_count = hand.count('A') for card in hand: if card in ['K', 'Q', 'J']: score += 10 elif card == 'A': score += 11 else: score += card while score > 21 and ace_count: score -= 10 ace_count -= 1 return score def compare(user_score, computer_score): """比较玩家和电脑得分并决定胜者""" if user_score > 21 and computer_score > 21: return "双方都爆牌了！平局。" if user_score == computer_score: return "平局！" elif computer_score == 21: return "庄家赢了！庄家拿到了Blackjack。"[^1] elif user_score == 21: return "恭喜您赢得了比赛！您拿到了Blackjack。" elif user_score > 21: return "很遗憾，您的牌超过了21点。庄家获胜。" elif computer_score > 21: return "庄家的牌超过21点了！您赢得比赛。"[^1] elif user_score > computer_score: return "恭喜您赢得了比赛！" else: return "很遗憾，庄家赢了！" def play_game(): """启动游戏""" user_cards = [] computer_cards = [] is_game_over = False for _ in range(2): user_cards.append(deal_card()) computer_cards.append(deal_card()) while not is_game_over: user_score = calculate_score(user_cards) computer_score = calculate_score(computer_cards) print(f"\n您的牌是 {user_cards} ，当前得分为：{user_score}") print(f"庄家的第一张牌是 {computer_cards[0]}") if user_score == 21 or computer_score == 21 or user_score > 21: is_game_over = True else: should_continue = input("输入'y'继续拿牌，或者'n'停止： ") if should_continue.lower() == 'y': user_cards.append(deal_card()) else: is_game_over = True while computer_score != 21 and computer_score < 17: computer_cards.append(deal_card()) computer_score = calculate_score(computer_cards) print(f"\n您的最终手牌为：{user_cards}, 最终得分为：{user_score}") print(f"庄家的手牌为：{computer_cards}, 最终得分为：{computer_score}") print(compare(user_score, computer_score)) if __name__ == "__main__": play_game() ``` #### 游戏说明 上述代码实现了一个简单的命令行版本的 BlackJack 游戏。它包含了以下几个核心功能： - **发牌机制**：通过 `deal_card` 函数模拟从一副标准扑克牌中抽取卡片。 - **计分规则**：函数 `calculate_score` 负责处理 A 的特殊计分情况（可以算作 1 或 11），确保不会超出合理范围。 - **胜负判定**：利用 `compare` 函数对比玩家与庄家的得分，得出最终结果。 - **交互体验**：允许玩家选择是否继续抽牌，并展示每一步的结果。
