Question

我的魔法8球代码由于某种原因赢了。基本代码有效，但它不会给出一个答案，它会启动一些永不停止的循环。有什么帮助吗？

import sys
import random

ans = True

while ans:
    question = input("Ask the magic 8 ball a question: (press enter to quit) ")

    answers = random.randint(1,8)

    if question == "":
        sys.exit()

    elif answers == 1:
        print ("It is certain")

    elif answers == 2:
        print ("Outlook good")

    elif answers == 3:
        print ("You may rely on it")

    elif answers == 4:
        print ("Ask again later")

    elif answers == 5:
        print ("Concentrate and ask again")

    elif answers == 6:
        print ("Reply hazy, try again")

    elif answers == 7:
        print ("My reply is no")

    elif answers == 8:
        print ("My sources say no")

一般来说，我会自己解决这个问题，但我已经看了两年

Answer 1

尝试在最后添加ans = False，如下所示：

import sys
import random

ans = True

while ans:
    question = input("Ask the magic 8 ball a question: (press enter to quit) ")

    answers = random.randint(1,8)

    if question == "":
        sys.exit()

elif answers == 1:
    print ("It is certain")

    elif answers == 2:
        print ("Outlook good")

    elif answers == 3:
        print ("You may rely on it")

    elif answers == 4:
        print ("Ask again later")

    elif answers == 5:
        print ("Concentrate and ask again")

    elif answers == 6:
        print ("Reply hazy, try again")

    elif answers == 7:
        print ("My reply is no")

    elif answers == 8:
        print ("My sources say no")
    ans = False

Answer 2

如果您不想要循环，请不要使用while。对于1次回应，请尝试：

import random

answers = ("It is certain","Outlook good","You may rely on it",\
           "Ask again later","Concentrate and ask again",\
           "Reply hazy, try again","My reply is no","My sources say no")

if input("Ask the magic 8 ball a question: (press enter to quit) "):
    print( answers[random.randint(0,len( answers )-1)] )
