我怎样才能用不可停止的循环修复这个代码？

Question

我将随机进行一个有趣的测验，包含 3 个问题，并提供 3 次猜测的机会。在我尝试执行后，我尝试了正确的答案，但继续循环并告诉我的答案不正确并且无法停止循环，我不知道为什么......有人可以帮我看一下吗？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 randomquizzes = [q1, q2, q3]  #catagorise to quizzesfor 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.

Answer 1

该行for answer in random.choice(quizzes)实际上获取一个随机测验字符串，然后迭代字符串中的每个字符；这就是为什么循环看起来没有停止，因为它迭代的项目比您预期的要多。

最初在循环中的行random.choice(quizzes), 不执行任何操作；该random.choice()函数从列表中返回一个随机项目。如果您不对返回值执行任何操作（例如打印它），那么什么也不会发生。

您原来的行if   quizzes == q1 and asking == 'A cold':不会起作用，因为quizzes是您的测验列表，所以检查quizzes == q1将始终是False。在我的代码中，由于我循环通过quizzesvia for quiz in quizzes，这意味着quiz在我的代码中是来自 的测验字符串quizzes，因此当我quiz == q1这样做时，可以正确地将当前quiz与q1,q2或进行比较q3。

a1我注意到您在、a2和中定义了答案a3，因此您可以简化代码并使用它们进行比较asking，例如asking == a1代替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.")

Answer 2

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

您还应该看看您的

elif guesses == 0:

现在，即使猜测次数为 0，玩家也能猜出。它可能应该是<=1。

您的代码将按照您想要的方式运行，如下所示：

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
