AttributeError: 'list' object has no attribute 'question' on Python

Question

我遇到了以下问题AttributeError，但是我检查了语法和缩进，没有发现错误。谁能帮我弄清楚哪里出了问题？

class Question():
    def __init__(self, question, answer):
        self.question = question
        self.answer = answer

question_prompts = [
    "What color are apples?\n(a) Red/Green\n(b) Purple\n(c) Orange\n",
    "What color are bananas?\n(a) Teal\n(b) Magenta\n(c) Yellow\n",
    "What color are strawberries?\n(a) Yellow\n(b) Red\n(c) Blue\n",
]

tasks = [
    Question(question_prompts[0], "a"),
    Question(question_prompts[1], "c"),
    Question(question_prompts[2], "b"),
]

def run_test(tasks):
    score = 0
    for items in tasks:
        answer = input(tasks.question)
        if answer == tasks.answer:
            score += 1
    print("You got " + str(score) + "/" + str(len(question_prompts)) + " correct")

run_test(tasks)

异常：

AttributeError: 'list' object has no attribute 'question'

Answer 1

您正在查看整个问题列表并尝试索引 .question 属性，以便它查看列表容器而不是单个对象，这将由 :-

answer = input(items.question)

As items 是在循环的每次传递中包含 Question 对象的变量。您还必须相应地更改答案检查
