如何在 Python 中存储用户输入并稍后调用？

Question

我想做一个能记住一些东西并且可以在以后展示的程序——比如人工智能

首先，我将向程序展示问题，例如“你今天过得怎么样？” 我还教它回答“好吧，你？”，类似的。

第二，当我问节目“你今天过得怎么样？” 或者“你好吗？”，它应该知道答案。

到目前为止，我有这个：

print ("Salut ! Am nevoie de ajutorul tau sa invat cateva propozitii...")
print ("Crezi ca ma poti ajuta ?")
answer1 = input("da/nu")

if (answer1=="da"):
  print ("Bun , acum tu poti sa pui intrebarea si raspunsul")
  print ("Spre exemplu , Primul lucru la inceput de linie trebuie sa fie intrebarea urmata de *?* ")
  print ("Apoi , raspunsul pe care eu trebuie sa il dau.")
  print ("Exemplu : Intrebare= Ce faci ? Raspuns= Bine , mersi :D")
question= "asd"
while (question != "stop"):
  question = input("The question: ")
  answer = input("The answer= ")

我应该怎么做才能存储问题，相应问题的答案，然后，当我输入诸如“密码”或任何特定单词之类的内容以测试它是否知道回答我的问题时？

Answer 1

尝试字典数据结构。 这种结构允许快速检索给定键（问题）的值（答案）。 这是一个示例程序和输出：

# dictionary to store the question-answer pairs
qa = {}

# store a series of question/answer pairs
while 1:
    question = input("add a question (or q to quit): ")

    if question == "q": 
        break

    answer = input("add the answer: ")
    qa[question] = answer

print("...")

# run the quiz
while 1:
    question = input("ask me a question (or q to quit): ")

    if question == "q": 
        break
    elif question in qa:
        print(qa[question])
    else:
        print("i'm not sure...")

示例运行：

Python 3.6.1 (default, Dec 2015, 13:05:11)
[GCC 4.8.2] on linux

add a question (or q to quit):  what is the meaning of life?
add the answer:  42
add a question (or q to quit):  what is my password?
add the answer:  1234
add a question (or q to quit):  q
...
ask me a question (or q to quit):  what is the meaning of life?
42
ask me a question (or q to quit):  what is my password?
1234
ask me a question (or q to quit):  help?
i'm not sure...
ask me a question (or q to quit):  q

如果您需要在程序运行后保留这些问题， 请将您的qa dict 写入文件或将问题和答案存储在SQLite等数据库中。

您可以使用字典。

answers = dict()
# usage is answers[question] = answer;
answers['How are you?'] = 'Good'
question = input()
if question in answers:
 print(answers[question])
