python - Python 初学者 - 多项选择测验程序遇到问题

Question

Python 初学者在这里使用 3.8.1 。

我目前正在研究一个分为两部分的多项选择测验程序。第一部分允许用户创建一系列问题+答案并使用 Pickle 模块保存它们。第二部分允许用户加载他们的保存数据并接受程序的测试。

我的问题是，在程序的第二部分，我想单独显示每个问题的多项选择选项，但我的程序最终会显示每个问题的多项选择，而不仅仅是当前提出的问题程序。

这是什么原因造成的，如何解决！

提前感谢您的帮助！

将您当前的 partTwo() 函数替换为：

def PartTwo():
        import pickle
        import random
        import os
        from time import sleep
        os.system('cls')

        while True:
                person = input("How much people will participate in this study session? : ")
                if person.isnumeric():
                        break
                else:
                        print("Please enter a valid answer.")

        for i in range(0, int(person)):

                os.system('cls')
                cx = pickle.load(open("Savedataone.dat", "rb"))
                ci = pickle.load(open("Savedatatwo.dat", "rb"))
                co = pickle.load(open("Savedatathree.dat", "rb"))
                print("Study session will begin soon...")
                sleep(2)
                questionNumber=0
                for cm in cx:
                        random.shuffle(cx)
                        print(cm["question"])
                        print(ci[questionNumber])
                        response = input("What was the correct answer (a, b, c or d)? : ")
                        if (response == cm["answer"]):
                                print("Good!")
                                questionNumber += 1
                                continue
                        else:
                                print("Wrong...")
                                sleep(0.2)
                                print("The correct answer was", cm, ".")
                                questionNumber+=1
                                continue

                        print("Study session is now over.")
                        sleep (1)
                print("Next person's study session will begin soon if needed.")
                sleep(1)
                print("Verification...")
                sleep(2.5)

        sleep(1.35)
        print("Study session is now over.")

我注意到您在“ci”中附加了 PartOne() 中的每个答案，但在 partTwo() 中，您只需打印 ci 而不指定打印所有内容的部分。

我添加了一个计数器（questionNumber）来跟踪当前提出的问题，该计数器用于指定要给出哪些可能的答案。
