创建对象列表python

我正在尝试创建测验,并且第二元素的questions数组中存在语法错误。我尝试通过`for循环将每个对象附加到数组,但是我需要每个问题都有正确的答案。

Questions类在一个不同的文件中:

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

这是主文件:

from Questions import Questions
questionsPrompt = ["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 score

runQuiz(questions)

2 个答案:

答案 0 :(得分:2)

正如Aran-Fey所评论的那样,列表项必须用逗号分隔。对于其他集合(如字典,集合等)也是如此。

questions = [
    Questions(questionsPrompt[0], "a"),
    Questions(questionsPrompt[1], "b"),
    Questions(questionsPrompt[2], "a")
]

答案 1 :(得分:1)

正如Aran-Fey指出的那样,您的语法不正确。

questions = [
    Questions(questionsPrompt[0], "a"),
    Questions(questionsPrompt[1], "b"),
    Questions(questionsPrompt[2], "a")
]

还有一点,您要创建的是列表,而不是数组。在语义和实现方面都存在差异,并且由于Python两者都有,所以这是一个重要的区别。
