我正在嘗試創建測驗，并且questions第二元素的數組中存在語法錯誤。我試圖通過`for循環將每個對象附加到數組，但是我需要每個問題都有正確的答案。Questions 類位于不同的文件中：class Questions:    def __init__(self, prompt, answer):        self.prompt = prompt        self.answer = answer這是主文件：from Questions import QuestionsquestionsPrompt = ["What does CPU stand for?\n(a) central procesing unit\n(b)controlled purification\n(c)computer unit",    "What is an advantage of a compiler?\n(a)slow to run each time\n(b)compiling takes a long time\n(c)easy to implement",    "The Operating System is a :\n(a)system software\n(b)application software\n(c)utility software"]questions = [    Questions(questionsPrompt[0], "a")    Questions(questionsPrompt[1], "b")    Questions(questionsPrompt[2], "a")]def runQuiz(questions):    score = 0    for question in questions:        answer = input(question.prompt)        if answer == question.answer:            score += 1    return scorerunQuiz(questions)
