### Python实现剪刀石头布模拟游戏代码（5局3胜） 以下是基于需求编写的Python代码，实现了剪刀石头布的游戏逻辑，并采用了5局3胜制： ```python import random def play_game(): choices = ['石头', '剪刀', '布'] win_conditions = [ ('石头', '剪刀'), # 石头赢剪刀 ('剪刀', '布'), # 剪刀赢布 ('布', '石头') # 布赢石头 ] player_score = 0 computer_score = 0 round_count = 0 print("欢迎来到剪刀石头布游戏！比赛为5局3胜制。") while True: if player_score >= 3 or computer_score >= 3: break round_count += 1 print(f"\n第{round_count}轮:") try: player_choice_index = int(input("请选择：0(石头), 1(剪刀), 2(布): ")) if not (0 <= player_choice_index <= 2): raise ValueError() except ValueError: print("输入错误，请重新选择有效值（0/1/2）。") round_count -= 1 continue player_choice = choices[player_choice_index] computer_choice = random.choice(choices) print(f"你出了：{player_choice}, 计算机出了：{computer_choice}") if player_choice == computer_choice: print("本轮结果：平局！") elif (player_choice, computer_choice) in win_conditions: print("本轮结果：你赢了！") player_score += 1 else: print("本轮结果：计算机赢了！") computer_score += 1 print(f"当前比分 - 你:{player_score}, 计算机:{computer_score}") if player_score > computer_score: result_message = "恭喜你赢得了比赛！" else: result_message = "很遗憾，计算机赢得了比赛。" print("\n比赛结束!") print(result_message) if __name__ == "__main__": play_game() ``` #### 说明 该代码通过`while`循环控制整个游戏流程，直到一方赢得三场为止[^1]。玩家每次从三个选项中选择一个（通过索引编号），而计算机则随机生成其选择。胜负判断依据预定义的胜利条件列表完成，确保逻辑清晰且易于维护[^2]。 --- ###
