### 实现5局3胜的剪刀石头布游戏 以下是基于Python编写的5局3胜制的剪刀石头布游戏代码示例： ```python import random class RockPaperScissorsGame: def __init__(self): self.choices = ['剪刀', '石头', '布'] self.player_score = 0 self.computer_score = 0 self.rounds_played = 0 def get_player_choice(self): while True: try: choice = int(input("请选择手势：1. 剪刀, 2. 石头, 3. 布 （输入对应的数字即可）")) - 1 if 0 <= choice < len(self.choices): return self.choices[choice] else: print("无效的选择，请重新输入！") except ValueError: print("请输入有效的数字！") def get_computer_choice(self): return random.choice(self.choices) def determine_winner(self, player_choice, computer_choice): if player_choice == computer_choice: return "平局" elif ( (player_choice == '剪刀' and computer_choice == '布') or (player_choice == '石头' and computer_choice == '剪刀') or (player_choice == '布' and computer_choice == '石头') ): return "玩家获胜" else: return "电脑获胜" def play_round(self): player_choice = self.get_player_choice() computer_choice = self.get_computer_choice() print(f"\n您选择了：{player_choice}") print(f"电脑选择了：{computer_choice}") result = self.determine_winner(player_choice, computer_choice) if result == "玩家获胜": self.player_score += 1 print("恭喜，本轮您获胜！") elif result == "电脑获胜": self.computer_score += 1 print("很遗憾，本轮电脑获胜！") else: print("本轮是平局！") self.rounds_played += 1 print(f"当前比分 - 您: {self.player_score}, 电脑: {self.computer_score}\n") def start_game(self): print("欢迎来到剪刀石头布游戏！比赛为5局3胜制。\n") while self.player_score < 3 and self.computer_score < 3: self.play_round() if self.player_score > self.computer_score: print("恭喜您赢得了整个比赛！") else: print("很遗憾，电脑赢得了整个比赛！") print("\n感谢您的参与！") if __name__ == "__main__": game = RockPaperScissorsGame() game.start_game() ``` #### 游戏逻辑说明 - **初始化部分**：定义了一个`RockPaperScissorsGame`类来封装游戏逻辑。游戏中包含了玩家分数、电脑分数以及已玩轮次计数器[^1]。 - **获取用户选择**：通过`get_player_choice()`函数让用户输入选项，并验证其有效性[^1]。 - **随机生成电脑选择**：利用`random.choice()`从预设列表中选取一项作为电脑的手势[^1]。 - **胜负判定**：在`determine_winner()`方法中实现了具体的胜负规则判断逻辑[^1]。 - **回合执行**：每一轮调用`play_round()`完成一次完整的比较并更新得分情况[^1]。 - **主循环控制**：当任意一方达到三场胜利时终止游戏[^1]。 #### 特点 此版本的游戏具有清晰结构化的设计思路，便于扩展与维护。例如可以轻松加入更多复杂的功能模块或者调整现有参数设置等操作[^3]。
