一个简单的python测验

Question

我正在编写一个 python 代码来用英语和新鲜的方式训练用户，根据选项，它会询问英语或法语问题并接受答案，然后它会根据列表检查输入的答案并增加分数，但是在第一个问题，我的代码停止运行

我试过包含一个 for 循环并使 while 循环成为函数的一部分，但什么都没有

#Python program to drill a student in french
import sys
option = 0
score=0
english_questions=['What is Thank you in French___?', 'What is you are welcome in French___?', 'What is no in French___?', 'What is Pardon in French___?', 'What is yes in French?___?']
french_questions =['What does Merci mean in English___? ', 'What does derien mean in English___?','What does No mean in English___?', 'What does pardon mean in English___?', 'What does oui mean in English___?' ]
french_answers =['merci', 'derien', 'no', 'pardon', 'oui']
english_answers=['thankyou', 'welcome', 'no', 'pardon', 'yes']
number_of_questions = 5
question_number = 0
print('Welcome to English-French Vocabulary Drill')
print('*********************************************')
print('To be drilled in English Press 1')
print('To be drilled in French Press 2')
print('*********************************************')

#a try except block to handle invalid option type
if option not in (1, 2):
     try:
         option=input('Please Enter option:')
     except:
         print('Invalid option, Please enter 1 or 2')

if option == 1:
   questions = english_questions
   answers = french_answers
elif option == 2:
    questions = french_questions
    answers = english_answers
#Function to check answer
def check_answer(user_answer, questions, answers):
    if user_answer in answers:
        print('')
        print('Correct')
        global score
        score +=1 
        global question_number
        question_number +=1
    else:
        print('')
        print('Incorrect, try again')
        global guesses 
        guesses +=1

global number_of_questions
while question_number < number_of_questions: 
    x = questions[question_number]
    user_answer = answers[question_number]
    print('')
    user_answer = input (x + ':')
    print (check_answer(user_answer, x, answers))
    print('')
    print('score : ' +str(score) )

我希望它打印出每个问题并一个接一个地请求答案，但我得到的是“正确无得分：0 W：”

Answer 1

此处： questions = questions[question_number] ，您为questions分配questions列表的值。 当循环第二次执行时，您将收到一封信，因为您将要求程序查找questions[question_number][question_number] 。 也许您应该尝试使用不同的变量名称？

Answer 2

除了 Rasgel 的回答之外，您应该将所有a =+ b语句更改为a += b以进行适当的递增。

Answer 3

我稍微更正了代码。 有很多错误。

• 您需要创建在代码中随处使用的全局变量，例如 score 和 guesses
• 您需要将 questions[question_number] 存储在一个新变量中。
• 您需要添加 while 循环来检查不正确的输入。

import sys


score  = 0
guesses= 0

english_questions=['What is Thank you in French___?', 'What is you are welcome in French___?', 'What is no in French___?', 'What is Pardon in French___?', 'What is yes in French?___?']
french_questions =['What does Merci mean in English___? ', 'What does derien mean in English___?','What does No mean in English___?', 'What does pardon mean in English___?', 'What does oui mean in English___?' ]
french_answers =['merci', 'derien', 'no', 'pardon', 'oui']
english_answers=['thankyou', 'welcome', 'no', 'pardon', 'yes']

number_of_questions = 5

question_number = 0

print('Welcome to English-French Vocabulary Drill')

print('*********************************************')
print('To be drilled in English Press 1')
print('To be drilled in French Press 2')
print('*********************************************')

#a try except block to handle invalid option type
option= int(input('Please Enter option:'))
while option not in (1,2) and type(option) == int:
   option = int(input("please enter valid option"))

if option == 1:
   questions = english_questions
   answers = french_answers
elif option == 2:
   questions = french_questions
   answers = english_answers

#Function to check answer

def check_answer(user_answer, answers):
   global question_number
   if user_answer in answers:
       print('')
       print('Correct')
       global score
       score += 1


   else:
       print('')
       print('Incorrect, try again')
       global guesses

       guesses = guesses+ 1
   question_number = question_number + 1

while question_number < number_of_questions: 
   cur_question = questions[question_number]
   user_answer = answers[question_number]
   print('')
   user_answer = input (cur_question + ':')
   print (check_answer(user_answer, answers))
   print('')

print('score : ' +str(score) )

Answer 4

在脚本顶部声明并初始化这些变量：

number_of_questions = 0
guesses = 0

然后将选项与字符串进行比较，这是用户输入：

if option == '1':
    questions = english_questions
    answers = french_answers
elif option == '2':
    questions = french_questions
    answers = english_answers

通过这些修复，它可以在不提升的情况下运行。
