Question

我想知道如何制作一个字典，该字典可以存储多个用户输入并在需要时将其打印出来。我已经用这段代码尝试过，但是我猜我错了，因为它不起作用：

def new_questions():
new_question = {}
while new_question:
    newly_added_question = raw_input('Please type the question:')
    newly_added_question_ans1 = raw_input('Please type the CORRECT answer:')
    newly_added_question_ans2 = raw_input('Please type an incorrect answer:')
    newly_added_question_ans3 = raw_input('Please type an incorrect answer:')
    new_question[newly_added_question] = newly_added_question_ans1
    new_question[newly_added_question] = newly_added_question_ans2
    new_question[newly_added_question] = newly_added_question_ans3

Answer 1

您可以尝试列出所有答案的列表并将其存储为：

new_question[newly_added_question] = [newly_added_question_ans1, newly_added_question_ans2, newly_added_question_ans3]

Answer 2

我建议使用字典来存储=IF(AND(S180>75,V180>75),S180+V180-150,IF(AND(S180>75,V180<75),S180-75,IF(AND(S180<76,V180>75),V180-75,IF(AND(S180<75,V180<75),""))))字典的每个值，如下所示：

new question

样本输出：

from pprint import pprint    

def new_questions():
    new_question = True

    questions = {}
    while new_question:
        question = raw_input('Please type the question:')
        ans1 = raw_input('Please type the CORRECT answer:')
        ans2 = raw_input('Please type an incorrect answer:')
        ans3 = raw_input('Please type an incorrect answer:')

        answers = {
            'correct': ans1,
            'incorrect_1': ans2,
            'incorrect_2': ans3
        }

        questions[question] = answers

        next_question = raw_input('\nAnother question? (Y/N): ')

        if next_question.lower() == 'n':
            new_question = False

    pprint(questions)

new_questions()

您可以使用Please type the question:How many e's in eternity? Please type the CORRECT answer:2 Please type an incorrect answer:3 Please type an incorrect answer:42 Another question? (Y/N): y Please type the question:Is this real? Please type the CORRECT answer:Yes. Please type an incorrect answer:No. Please type an incorrect answer:Maybe? Another question? (Y/N): n {"How many e's in eternity?": {'correct': '2', 'incorrect_1': '3', 'incorrect_2': '42'}, 'Is this real?': {'correct': 'Yes.', 'incorrect_1': 'No.', 'incorrect_2': 'Maybe?'}}，questions[question]['correct']等访问每个问题的答案。

Answer 3

从您的代码看来，每当您为问题分配新答案时，您似乎都将覆盖字典中键的值。

尝试一些容器来存储密钥的值。也就是说，要在字典中保存问题的答案，您可以将列表用作容器。参见下面的示例。

result = {}  #Empty dictionary

def new_question(result):
  question = input("Enter the question: ")
  ans1 = input("Enter the Correct answer ")
  ans2 = input("Enter the Incorrect answer ")
  ans3 = input("Enter the another Incorrect answer ")
  answers = [ans1,ans2,ans3]  #storing answers in a list
  result[question] = answers  #setting answers to question

new_question(result) #add questions and answers by calling this fuction, call this in a loop if multiple questions
print(result) # print all the questions and answers

注意：如果您定义了答案的选项数量，那么您也可以为用户输入添加循环。
