Python 简单测验-如何链接变量？

我一直在努力找出正确答案与正确问题的匹配方法。现在，如果用户的答案与任何答案相等，则返回正确答案。请帮忙

easy_question = "The capitol of West Virginia is __1__"
medium_question = "The device amplifies a signal is an __2__"
hard_question = "A program takes in __3__ and produces output."

easy_answer = "Charleston"
medium_answer = "amplifier"
hard_answer = "input"

questions_and_answers = {easy_question: easy_answer, 
                    medium_question: medium_answer,
                    hard_question: hard_answer}
#print(easy_answer in [easy_question, easy_answer])
#print(questions_and_answers[0][1])

print('This is a quiz')
ready = input("Are you ready? Type Yes.")
while ready != "Yes":
    ready = input("Type Yes.")
user_input = input("Choose a difficulty: Easy, Medium, or Hard")

def choose_difficulty(user_input):
    if user_input == "Easy":
        return easy_question
    elif user_input == "Medium":
        return medium_question
    elif user_input == "Hard":
        return hard_question
    else:
        print("Incorrect")
        user_input = input("Type Easy, Medium, or Hard")
print(choose_difficulty(user_input))


answer = input("What is your answer?")
def check_answer(answer):
    if answer == easy_answer:
        return "Correct"
    elif answer == medium_answer:
        return "Correct"
    elif answer == hard_answer:
        return "Correct"
 print(check_answer(answer))

您需要跟踪

问题

：

question = choose_difficulty(user_input)
print(question)

answer = input("What is your answer?")
def check_answer(question, answer):
    if questions_and_answers[question] == answer:
        return "Correct"
    return "Incorrect"
print(check_answer(question, answer))

你可以做很多很酷的事情，但这只是一个可以解决你问题的小例子

编辑：

你什么时候做的

questions_and_answers = {easy_question: easy_answer, 
                medium_question: medium_answer,
                hard_question: hard_answer}

您创建了一个字典（或Python中的dict）。看见基本上，您可以按第一个术语（问题）进行查找，然后返回第二个术语（答案）。

我的方法是：创建两个变量，x和y。如果用户选择“Easy”，则将x设置为1，“Medium”将其设置为2，依此类推。然后你问他一个答案。简单问题的答案如果正确，则将y设置为1，中间设置为2，依此类推。然后检查x==y。如果是，那么他对问题的回答是正确的。

除了在

check\u answer

中返回

'Correct'

之外，您没有尝试返回任何东西。因为

If/elif

将继续检查条件，直到某个条件为真，然后您将满足

返回

条件。在

check_-answer

中，您只需继续，直到找到正确的内容。这将不起作用，也无法解决原始代码的限制。这篇文章将一个问题映射到字典中的一个正确答案，而且这个问题已经有了比你提供的更全面的答案。谢谢！那么，“如果问题和回答[问题]==回答”到底在做什么？
