帮我写一段学生成绩管理系统python代码

当然可以！以下是一个简单的学生成绩管理系统的 Python 代码示例：

class Student:
    def __init__(self, name, scores):
        self.name = name
        self.scores = scores

class GradeBook:
    def __init__(self):
        self.students = []

    def add_student(self, student):
        self.students.append(student)

    def get_student_average(self, student):
        return sum(student.scores) / len(student.scores)

    def get_class_average(self):
        total_scores = 0
        num_students = len(self.students)
        for student in self.students:
            total_scores += sum(student.scores)
        return total_scores / (num_students * len(student.scores))

# Example usage:
bob = Student("Bob", [90, 80, 70])
jane = Student("Jane", [95, 85, 75])
gradebook = GradeBook()
gradebook.add_student(bob)
gradebook.add_student(jane)
bob_average = gradebook.get_student_average(bob)
jane_average = gradebook.get_student_average(jane)
class_average = gradebook.get_class_average()
print("Bob's average score:", bob_average)
print("Jane's average score:", jane_average)
print("Class average score:", class_average)

这个代码定义了两个类：`Student` 和 `GradeBook`。`Student` 类包含学生的姓名和分数，`GradeBook` 类管理学生列表并提供方法来计算学生和整个班级的平均分数。你可以根据自己的需要进行修改和扩展。
