Python答题游戏while与for循环逻辑错误及答案识别问题求助

现有代码问题梳理 #

• 修改后的代码没有遍历所有备选答案，直接取列表第一个元组做匹配，导致除了第一个答案的内容外，其余正确答案全部判定为错误
• 取值逻辑错误：item = possible_answers后取item[0]拿到的是完整答案元组，需要取元组的第一个元素才是答案文本内容
• 多余的内层while循环无实际作用，外层循环本身已做失误次数校验

正确实现逻辑 #

每次获取用户输入后，遍历所有备选答案做匹配：

1. 匹配到对应答案：累加对应分值，本次作答不扣失误次数
2. 遍历完所有答案都未匹配：判定为答错，扣除1次失误次数

修复后完整代码 #

question = "Name something a baby does that would be unacceptable in a roommate."
possible_answers = [("CRY/AT 3 A.M.", 39), ("POO/WET SELF", 28), ("PUKE/ON ME", 9), ("BURP", 8), ("MAKE MESS/TOSS FOOD", 5), ("FART", 4), ("PEE IN MY FACE", 3), ("NURSE/ON MY NIPS", 2)]

player_strikes_left = 3
player_score = 0

while player_strikes_left > 0:
    player_answer = input("player answer: ").upper()
    is_correct = False
    earned_points = 0
    # 遍历所有备选答案匹配
    for answer_text, points in possible_answers:
        if player_answer in answer_text:
            is_correct = True
            earned_points = points
            break # 匹配到就跳出，不用继续遍历
    if is_correct:
        print("回答正确")
        player_score += earned_points
    else:
        print("回答错误")
        player_strikes_left -= 1

print(f'最终得分: {player_score}, 剩余失误次数: {player_strikes_left}')

额外优化说明 #

如果需要避免用户重复答同一个答案重复得分，可以加一个已答对答案的标记列表，每次匹配到后先判断是否已经答过，没答过再加得分，逻辑如下：
初始化加一行answered = []，匹配到正确答案后判断if answer_text not in answered，加分后把answer_text加入answered列表即可。
