How to store user input in Python and call it later?

Question

I want to make a program that remembers something and can show it later on - like A.I.

First, I will show the program the question, like "How are you today?" and I also teach it the answer "Fine , you?", something like that.

Second, when I ask the program "How are you today?" or "How are you?", it should know the answer.

So far, I have this:

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= ")

What should I do to be able to store the question, the answer for the respective question, then, when I input something like "Password" or any specific word to be able to test if it knows to reply my questions?

Will the program continue to run? If so, why not just store questions and answers in a variable, e.g. a dictionary, and retrieve the answers from there? — Dux, Jun 03 '18 at 20:50

Try a dictionary data structure. This structure allows fast retrieval of a value (answer) given a key (question). Here's a sample program and output:

# 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...")

Sample run:

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

If you need to persist these questions beyond the program's run, write your qa dict to a file or store the questions and answers in a database such as SQLite.

Thanks . I have one more question . How do i store them to work in another session ? Not teach it every time ? — Gusto Pop, Jun 03 '18 at 21:14
You can pickle the dictionary and write it to a file, then retrieve it from file on each program run: https://stackoverflow.com/questions/19201290/how-to-save-a-dictionary-to-a-file — ggorlen, Jun 03 '18 at 21:23

You can use dictionaries.

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