### Python 实现剪刀石头布游戏（5局3胜） 以下是一个基于 Python 的剪刀石头布小游戏代码示例，采用了 5 局 3 胜制的设计。此版本改进了用户体验，并增加了清晰的胜负判定逻辑。 ```python import random def get_player_choice(): """ 获取玩家的选择 """ choices = {'1': '剪刀', '2': '石头', '3': '布'} while True: choice = input("请选择手势（输入对应数字）：\n1. 剪刀\n2. 石头\n3. 布\n您的选择：").strip() if choice in choices: return choices[choice] else: print("无效输入，请重新选择！") def get_computer_choice(): """ 随机生成计算机的选择 """ return random.choice(['剪刀', '石头', '布']) def determine_round_winner(player_choice, computer_choice): """ 判定单轮比赛的赢家 """ 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 "玩家胜利" else: return "电脑胜利" def play_game(): """ 主游戏逻辑 """ player_score = 0 computer_score = 0 rounds_played = 0 max_rounds = 5 # 总共玩 5 局 win_threshold = 3 # 获得 3 分即可赢得比赛 print("欢迎来到剪刀石头布游戏！本场为 5 局 3 胜制。\n") while rounds_played < max_rounds and player_score < win_threshold and computer_score < win_threshold: player_choice = get_player_choice() computer_choice = get_computer_choice() print(f"\n您选择了：{player_choice}") print(f"电脑选择了：{computer_choice}") result = determine_round_winner(player_choice, computer_choice) if result == "玩家胜利": player_score += 1 print("恭喜！本轮您获胜！") elif result == "电脑胜利": computer_score += 1 print("很遗憾，本轮电脑获胜！") else: print("本轮双方打成平手！") print(f"当前比分 - 您：{player_score} | 电脑：{computer_score}\n") rounds_played += 1 if player_score >= win_threshold: print("最终结果：恭喜您赢得了整场比赛！🎉") elif computer_score >= win_threshold: print("最终结果：很遗憾，电脑赢得了整场比赛！🤖") else: print("最终结果：比赛结束，双方未分胜负！🤝") play_game() ``` --- #### 游戏特点说明 - **用户交互友好**：程序提示用户通过输入对应的数字来选择手势，避免复杂指令。 - **随机性保障公平**：`get_computer_choice` 方法使用 `random.choice` 来模拟电脑的随机决策[^2]。 - **清晰的胜负判定**：每一轮的结果都会立即显示给用户，并更新总分数[^1]。 - **固定回合数与得分条件**：设定总共 5 局，先达到 3 分者获胜[^3]。 --- ###
