【问题描述】：
所以我希望能够使用词典制作多项选择测验程序。我有一本字典，其中所有问题为键，答案为值，第二本字典为空。我想将某人可能遇到的所有不正确的问题附加到空字典中。我想这样做是为了允许用户重新参加考试，但仅限于他们回答错误的问题。然而，我无法找到一种方法来将一个列表中的键和值附加到另一个列表中而不是具体的。
下面是我的代码：
def intro():
print("Hello and welcome to the random questions test")
global name
name = input("what is your name? " + "\n" + "\n")
if name == "":
print("Enter a valid name!")
name = input("what is your name? " + "\n" + "\n")
else:
ans2 = input("\n" + "Hello " + name + " Are you sure you want to take the exam? (yes/no)" + "\n" + "\n")
if ans2 == "no":
print("\n" + "aw man, until next time " + name + "!" + "\n")
elif ans2 == "yes":
print("\n" + "Okay!" + "\n")

我想我会用键（“q1”，“q2”，......“q15”）重新定义您的初始字典，然后字典值可以是一个元组（“问题文本”，“正确答案值”。您可以根据键、值对在字典中循环。然后用 dict[key][0] 提出问题并比较 dict[kay][1] 的答案。如果答案正确，请更新答案计数，如果答案不正确，将问题键存储在重新测验列表中，因此只有答案不正确的问题才会被重新提出。
-
字典是一个键->值对，根据定义。如果你想追加你可能会更好用一个列表。如果您真的希望能够“附加”stackoverflow.com/questions/10058140/… ...，您也可以使用有序的字典。但是，我仍然不明白您为什么要“附加”到字典 - 列表和字典都是可迭代。

欢迎来到 SO！查看tour。这是太多的代码。请发送minimal reproducible example。你可以edit这个问题。如果您想了解更多提示，请查看How to Ask。

根据我的回答，问题标题不匹配。我远离键值对，而是使用列表中的元组来使其正常工作。这更像是一个列表解决方案，而不是一个 dict 解决方案。 list vs. dict 的原因是跟踪未回答的问题并快速遍历它们。
