Python多选题代码出现IndexError: list index out of range错误求助

错误原因 #

question_prompts列表中的三个字符串未用逗号分隔，Python会自动将相邻的字符串字面量拼接成一个字符串，导致该列表实际仅包含1个元素，尝试访问索引1和2时自然触发索引越界错误。

修正后的代码 #

Question.py（无需修改）

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

student.py（修正列表元素分隔及输出格式）

from Question import Question 

question_prompts = [
    'what color are apples?\n(a) red\n(b) purple\n(c) orange\n\n',
    'what color are bananas?\n(a) teal\n(b) black\n(c) yellow\n\n',
    'what color are oranges?\n(a) white\n(b) orange\n(c) red\n\n'
]

questions = [
    Question(question_prompts[0], 'a'),
    Question(question_prompts[1], 'c'),
    Question(question_prompts[2], 'b'),
]

def run_test(questions):
    score = 0
    for question in questions:
        answer = input(question.prompt)
        if answer == question.answer:
            score += 1
    print('you got ' + str(score) + '/' + str(len(questions)) + ' correct')

run_test(questions)

注：顺便修正了打印语句中correct前缺失的空格，避免输出格式不规范。
