如何使用无法停止的循环修复此代码？

Question

我打算做一个有趣的小测验，随机 3 个问题，并给出 3 次猜测的机会。

在我尝试执行后，我尝试了正确的答案，但一直循环，并告诉我答案不正确，无法停止循环，我不知道为什么....

谁能帮我看看？

q1 = 'What can one catch that is not thrown?'
a1 = 'A cold'
q2 = 'If you had only one match and entered a dark room containing an oil lamp, some kindling wood, and a newspaper, which would you light first?'
a2= 'The match'
q3 = 'Some months have 31 days, others have 30 days, but how many have 28 days?'
a3= 'All the months'

import random
quizzes = [q1, q2, q3]  #catagorise to quizzes

for answer in random.choice(quizzes):
    guesses = 3  # limits to 3 guesses
    random.choice(quizzes)
    asking = input('Your Answer is?\n')
    if   quizzes == q1 and asking == 'A cold':
        print( 'Bingo!!')
        break
    elif quizzes == q2 and asking == 'The match':
        print( 'Bingo!!')
        break
    elif quizzes == q3 and asking == 'All the months':
        print( 'Bingo!!')
        break
    elif guesses == 0:
        print( 'Sorry, you are reached the maximum guesses. Bye~now~')
    else:
        guesses -= 1  #reducing the max. guesses of 3 to 2 to 1
        print( "Sorry, it's incorrect.")
    result = asking

Answer 1

你的问题是猜测的位置。现在它在你的 for 循环中。把它放在你的 for 循环之外，它应该可以工作。

你也应该看看你的

elif guesses == 0:

现在玩家即使猜0次也能猜到。它可能应该是 <=1。

您的代码将按您希望的方式运行：

q1 = 'What can one catch that is not thrown?'
a1 = 'A cold'
q2 = 'If you had only one match and entered a dark room containing an oil lamp, some kindling wood, and a newspaper, which would you light first?'
a2= 'The match'
q3 = 'Some months have 31 days, others have 30 days, but how many have 28 days?'
a3= 'All the months'

import random
quizzes = [q1, q2, q3]  #catagorise to quizzes
guesses = 3    

for answer in random.choice(quizzes):
           # limits to 3 guesses
           random.choice(quizzes)

           asking = input('Your Answer is?\n')
           if   quizzes == q1 and asking == 'A cold':
                  print( 'Bingo!!')
                  break
           elif   quizzes == q2 and asking == 'The match':
                  print( 'Bingo!!')
                  break
           elif   quizzes == q3 and asking == 'All the months':
                  print( 'Bingo!!')
                  break
           elif   guesses <=1:
                  print( 'Sorry, you are reached the maximum guesses. Bye~now~')
                  exit()

                  
           else:
                  guesses -= 1        #reducing the max. guesses of 3 to 2 to 1
                  print( "Sorry, it's incorrect.")
            
           result = asking

Answer 2

for answer in random.choice(quizzes)行实际上是获取一个随机的问题字符串，然后遍历字符串中的每个字符；这就是循环似乎没有停止的原因，因为它迭代的项目比您预期的要多。

你原来在循环中的那一行，random.choice(quizzes)，什么都不做； random.choice() 函数 returns 列表中的随机项。如果您没有对返回值做任何事情，比如打印它，那么什么也不会发生。

像 if quizzes == q1 and asking == 'A cold': 这样的原始行将不起作用，因为 quizzes 是您的测验列表，因此检查 quizzes == q1 将始终是 False。在我的代码中，由于我通过 for quiz in quizzes 循环遍历 quizzes，这意味着我代码中的 quiz 是来自 quizzes 的测验字符串，所以当我执行 quiz == q1，正确地将当前 quiz 与 q1、q2 或 q3.

进行比较

我注意到您在 a1、a2 和 a3 中定义了您的答案，因此您可以简化代码并使用它们与 asking 进行比较，例如asking == a1 而不是 asking == 'A cold'.

import random
quizzes = [q1, q2, q3]  #catagorise to quizzes
random.shuffle(quizzes)  # randomize the quiz order

for quiz in quizzes:  # loop through the list of quizzes
    guesses = 3     # limits to 3 guesses
    print(quiz)     # prompt the user with the quiz question
    while True:     # keep asking for answers until guesses run out, or the user gets a correct answer
           asking = input('Your Answer is?\n')
           if     quiz == q1 and asking == a1:
                  print( 'Bingo!!')
                  break
           elif   quiz == q2 and asking == a2:
                  print( 'Bingo!!')
                  break
           elif   quiz == q3 and asking == a3:
                  print( 'Bingo!!')
                  break
           elif   guesses == 0:
                  print( 'Sorry, you are reached the maximum guesses. Bye~now~')
                  break
           else:
                  guesses -= 1        #reducing the max. guesses of 3 to 2 to 1
                  print( "Sorry, it's incorrect.")
