能给份代码吗

当然可以,以下是一个简单的示例代码,实现了试题库、试卷和判卷模块的基本功能。由于篇幅有限,代码仅供参考,可能需要根据具体需求进行修改。
```python
class Question:
def __init__(self, stem, options, answer):
self.stem = stem
self.options = options
self.answer = answer
class QuestionBank:
def __init__(self):
self.questions = []
def add_question(self, question):
self.questions.append(question)
def remove_question(self, question):
self.questions.remove(question)
def get_random_questions(self, num):
return random.sample(self.questions, num)
class Paper:
def __init__(self, questions):
self.questions = questions
self.answers = {}
def answer_question(self, question, answer):
self.answers[question] = answer
def get_score(self):
score = 0
for question, answer in self.answers.items():
if answer == question.answer:
score += 1
return score
class Grader:
def __init__(self, paper):
self.paper = paper
def grade(self):
return self.paper.get_score()
# Example usage
question1 = Question("What is the capital of France?", ["Paris", "London", "Berlin", "Madrid"], "Paris")
question2 = Question("What is the largest planet in the solar system?", ["Mercury", "Venus", "Earth", "Jupiter"], "Jupiter")
question3 = Question("What is the highest mountain in the world?", ["K2", "Mount Everest", "Makalu", "Cho Oyu"], "Mount Everest")
question_bank = QuestionBank()
question_bank.add_question(question1)
question_bank.add_question(question2)
question_bank.add_question(question3)
paper = Paper(question_bank.get_random_questions(2))
paper.answer_question(question1, "Paris")
paper.answer_question(question2, "Jupiter")
grader = Grader(paper)
score = grader.grade()
print("Your score is:", score)
```
以上代码实现了试题、试题库、试卷和判卷模块的基本功能。其中,Question类表示试题,QuestionBank类表示试题库,Paper类表示试卷,Grader类表示判卷模块。
在示例代码中,首先创建了三个试题,并将它们添加到试题库中。然后,从试题库中随机抽取了两道题,生成了一份试卷。在答题过程中,学生依次回答了两个问题,并将答案保存到试卷中。最后,判卷模块计算出了学生的得分,并输出到控制台上。
当然,具体的实现方式可以根据具体需求进行修改和扩展。
