如何开发一个高效的学生成绩管理系统？

由于篇幅原因，我无法提供完整的学生成绩管理系统源码，但我可以给你一个简单的Python示例，你可以根据这个示例进行扩展和修改以满足你的需求。

class Student:
    def __init__(self, name, student_id):
        self.name = name
        self.student_id = student_id
        self.scores = {}
    def add_score(self, course, score):
        self.scores[course] = score
    def get_average_score(self):
        total_score = sum(self.scores.values())
        num_courses = len(self.scores)
        return total_score / num_courses if num_courses > 0 else 0
    def __str__(self):
        return f"{self.name} ({self.student_id}): {self.scores}"
class Gradebook:
    def __init__(self):
        self.students = {}
    def add_student(self, student):
        self.students[student.student_id] = student
    def remove_student(self, student_id):
        if student_id in self.students:
            del self.students[student_id]
    def get_student(self, student_id):
        return self.students.get(student_id)
    def list_students(self):
        for student in self.students.values():
            print(student)
    def save_to_file(self, filename):
        with open(filename, 'w') as file:
            for student in self.students.values():
                file.write(f"{student.name},{student.student_id},{','.join([f'{k}:{v}' for k, v in student.scores.items()])}
")
    def load_from_file(self, filename):
        with open(filename, 'r') as file:
            for line in file:
                parts = line.strip().split(',')
                name = parts[0]
                student_id = parts[1]
                scores = {parts[i]: int(parts[i + 1]) for i in range(2, len(parts), 2)}
                student = Student(name, student_id)
                student.scores = scores
                self.add_student(student)
if __name__ == "__main__":
    gradebook = Gradebook()
    # 添加学生和成绩
    student1 = Student("张三", "001")
    student1.add_score("数学", 90)
    student1.add_score("英语", 85)
    gradebook.add_student(student1)
    student2 = Student("李四", "002")
    student2.add_score("数学", 80)
    student2.add_score("英语", 75)
    gradebook.add_student(student2)
    # 列出所有学生及其成绩
    gradebook.list_students()
    # 保存到文件
    gradebook.save_to_file("gradebook.txt")
    # 从文件加载数据
    new_gradebook = Gradebook()
    new_gradebook.load_from_file("gradebook.txt")
    new_gradebook.list_students()

这个示例包含了两个类：Student 和Gradebook。Student 类用于存储学生的姓名、学号和成绩，Gradebook 类用于管理学生列表，包括添加、删除、查找学生以及将学生信息保存到文件和从文件中加载学生信息。
