如何让 Python 只允许特定答案

Question

你好，我需要帮助我一直在做的这个程序，这是一个会问用户琐事问题然后计算用户智商的程序，我设法让程序问用户问题，然后添加一个 1当用户正确回答问题时，名为“IQ”的列表，然后我让计算机计算列表中有多少个，以检查用户得到的分数。

然后我第二天尝试让它，如果你没有输入指定答案之一，程序会让你再次输入答案，并输出一条消息，要求再次输入你的答案。

我对编程还很陌生，所以任何帮助或批评都将不胜感激。

import time

print("Welcome! This is the special IQ quiz...")
time.sleep(2)
print("You start at 60 IQ and you get 20 IQ for each question you get correct...")
time.sleep(2)
print("Let's see how smart you are, good luck!\n")
time.sleep(1)

Answer 1

首先，最好将所有问题和答案与逻辑分开。

其次，您可以通过遍历问题列表来避免每个问题的代码重复。

第三，使用while True循环不断地问同样的问题。

QUESTIONS = [{"Question": "What's the name of the river that runs through Egypt?",
              "Answers": ["The Nile", "The Mississippi River", "The Yangtze River", "The Amazon River"],
              "CorrectAnswer": "The Nile"},
             {"Question": "Who was the Prime Minister before Theresa May?",
              "Answers": ["David Cameron", "John Mayor", "Tony Blair", "Harold Wilson"],
              "CorrectAnswer": "David Cameron"}]

score = 0
for question in QUESTIONS:
    while True:
        answer = input(question['Question'] + '\n>> ' + '\n>> '.join(question['Answers']) + '\n')
        if answer in question['Answers']:
            if answer == question['CorrectAnswer']:
                score += 1
            break
        else:
            print('That is not a valid answer, make sure to input one of\nthe answers and if you did, make sure its written how it is displayed in the question...')

iq = score * 20 + 60
if score == 0:
    print(f'You answered none of the questions correctly so you have an IQ of {iq}')
elif 0 < score < len(QUESTIONS):
    print(f'You answered {score} out of {len(QUESTIONS)} questions correctly so you have an IQ of {iq}')
elif score == len(QUESTIONS):
    print(f'You answered all of the questions correctly so you have an IQ of {iq}')

样本输出：

What's the name of the river that runs through Egypt?
>> The Nile
>> The Mississippi River
>> The Yangtze River
>> The Amazon River
The Nile
Who was the Prime Minister before Theresa May?
>> David Cameron
>> John Mayor
>> Tony Blair
>> Harold Wilson
John Mayor
You answered 1 out of 2 questions correctly so you have an IQ of 80

Answer 2

你可以这样做 -

pass = True
while pass:
    qustn1 = input("What's the name of the river that runs through Egypt?\n>> The Mississippi River\n>> The Nile\n>> The Yangtze River\n>> The Amazon River\n")
    if qustn1 == "The Nile":
        iq.append(1)
        qustn_answrd.append(1)
        pass = False
    elif qustn1 == "The Mississippi River" or "The Yangtze River" or "The Amazon River":
        qustn_answrd.append(1)
        pass = False
    elif qustn1 != "The Nile" or "The Mississippi River" or "The Yangtze River" or "The Amazon River":
        print("That is not a valid answer, make sure to input one of\nthe answers and if you did, make sure its written how it is displayed in the question...")
        pass = False
    else:
        pass = True

所以你做 bool of pass 并检查它是真还是假
