隨機化來自WebAPI的問題并列印出錯誤的答案

我想從一個有很多問題的網路 API 中得到 10 個隨機問題，但我似乎沒有讓它起作用。現在我得到KeyError: 'prompt'，但我不知道該功能是否正確，因為我一直在嘗試一些不同的選項。

我還試圖在最后列印出您出錯的問題，但也沒有運氣。

import random
import requests
from random import randint

url = ""
the_questions = requests.get(url).json()
print("------ Welcome to Python quiz ------")


def random_question():
    data = the_questions['prompt']
    random_index = randint(0, len(data)-1)
    return data[random_index]['prompt']


def get_correct_answers(answers):
    res = []
    for ans in answers:
        if ans['correct']:
            res.append(ans['answer'])
    return res


def get_numeric(prompt, max_value,):
    while True:
        try:
            res = int(input(prompt))
        except ValueError:
            print("Answer only with a number!")
            continue
        if 0 < res < max_value:
            break
        else:
            print("Invalid answer option!")
    return res


def main():
    score = 0
    for questions in the_questions['questions']:
        #print(questions['prompt'])
        print(random_question())

        for i, a in enumerate(questions['answers'], start=1):
            print(f"[{i}] {a['answer']}")
        user_answer = get_numeric("> ", len(questions['answers'])   1)

        if questions['answers'][user_answer - 1]['correct']:
            score  = 1
            print(f"Right!")
        else:
            all_correct = ", ".join(get_correct_answers(questions['answers']))
            print(f"Wrong, right is: {all_correct}")
    print(f"You got {score} points of {len(the_questions['questions'])} possible!")

API 示例

{"questions":[{"id":"1","prompt":"Which functions is used to write out text in the terminal?","answers":[{"answer":"print","correct":true},{"answer":"input","correct":false},{"answer":"import","correct":false},{"answer":"sys.exit","correct":false}]}

uj5u.com熱心網友回復：

錯誤顯示密鑰有問題，prompt您僅在random_question().

如果您使用print()查看變數中的值，random_question()那么您將看到您需要

    data = the_questions['questions']

代替

    data = the_questions['prompt']

至于我的變數名稱是誤導性的。您應該data對來自 API 的所有資訊使用 name ，然后才有questions = data['questions']意義。

編輯：

我的版本與 random.shuffle()
