Python猜拳游戏分数不更新故障：始终显示双方分数为0

核心问题1：计分板未实时更新 #

你定义的scoreboard是在初始化user_score和comp_score后生成的静态字符串，后续分数变化时，这个字符串不会自动同步新的分数值。每次分数变动后，必须重新生成计分板的字符串才能显示最新分数。

核心问题2：循环终止条件错误 #

当前循环条件while user_score < 3 or comp_score < 3意味着只要任意一方分数没到3就会一直循环，这会导致游戏无法正常结束（比如玩家到3分后，电脑分数没到，游戏仍会继续）。正确的逻辑应该是双方都没到3分时才继续游戏，所以要把or改成and。

修复后的完整代码 #

import random
def rps():
    user_score = 0 
    comp_score = 0
    # 修正循环终止条件：双方均未达3分时继续游戏
    while user_score < 3 and comp_score < 3:
        choice = ['r', 'p', 's']
        user = input('Choose [r] [p] or [s]: ')
        user = user.lower()
        comp = random.choice(choice)
        outcome = f"You chose {user} and I chose {comp}"
        
        if user == comp:
            # 每次打印前重新生成计分板
            scoreboard = f'You: {user_score} \nComp: {comp_score}'
            print(scoreboard)
            print(outcome)
            print('Tie Game')
        elif (user == 'r' and comp == choice[2]) or (user == 'p' and comp == choice[0]) or (user == 's' and comp == choice[1]):
            user_score += 1
            # 分数更新后立即生成最新计分板
            scoreboard = f'You: {user_score} \nComp: {comp_score}'
            print(scoreboard)
            print(outcome, '\nYou win!')
        else:
            comp_score += 1 
            # 分数更新后立即生成最新计分板
            scoreboard = f'You: {user_score} \nComp: {comp_score}'
            print(scoreboard)
            print(outcome, '\nI win')
    # 游戏结束时打印最终计分板
    final_scoreboard = f'You: {user_score} \nComp: {comp_score}'
    print(final_scoreboard)

rps()

额外优化建议 #

可以把计分板生成逻辑封装成一个小函数，避免重复代码：

def get_scoreboard(user_score, comp_score):
    return f'You: {user_score} \nComp: {comp_score}'

之后在需要打印计分板的地方，直接调用print(get_scoreboard(user_score, comp_score))即可。
