以下是一个示例代码,用于实现对选择题和多选题评估选项的黑板考试的解决方法:
class Exam:
def __init__(self, questions):
self.questions = questions
def evaluate(self):
for question in self.questions:
if isinstance(question, MultipleChoiceQuestion):
self.evaluate_multiple_choice(question)
elif isinstance(question, MultipleAnswerQuestion):
self.evaluate_multiple_answer(question)
else:
print("Unsupported question type.")
def evaluate_multiple_choice(self, question):
# 在这里实现对选择题的评估逻辑
pass
def evaluate_multiple_answer(self, question):
# 在这里实现对多选题的评估逻辑
pass
class Question:
def __init__(self, text):
self.text = text
class MultipleChoiceQuestion(Question):
def __init__(self, text, choices, answer):
super().__init__(text)
self.choices = choices
self.answer = answer
class MultipleAnswerQuestion(Question):
def __init__(self, text, choices, answers):
super().__init__(text)
self.choices = choices
self.answers = answers
# 创建选择题和多选题的实例
question1 = MultipleChoiceQuestion("What is the capital of France?", ["A. London", "B. Paris", "C. Berlin", "D. Rome"], "B")
question2 = MultipleAnswerQuestion("Which of the following are fruits?", ["A. Apple", "B. Carrot", "C. Banana", "D. Tomato"], ["A", "C"])
# 创建考试实例并进行评估
exam = Exam([question1, question2])
exam.evaluate()
上述代码示例中,Exam
类表示一个考试,其中包含了多个问题(题目)。在 evaluate
方法中,通过遍历每个问题并判断其类型,实现对选择题和多选题的评估逻辑。
Question
类是问题的基类,包含了问题的文本内容。MultipleChoiceQuestion
类继承自 Question
类,表示选择题,其中包含了选项和正确答案。MultipleAnswerQuestion
类同样继承自 Question
类,表示多选题,其中包含了选项和正确答案的列表。
在实际的评估逻辑中,你可以根据实际需求来编写代码,对选择题和多选题进行评估。以上只是一个示例,具体的评估逻辑需要根据具体要求来实现。
