学生成绩管理系统python代码

当然，我可以帮你概述一个简单的学生成绩管理系统的基本结构。这个系统通常包括学生的数据（如姓名、ID、课程和分数等）的存储和管理功能。以下是一个基础的命令行版本的示例：

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

    def add_score(self, course, score):
        if course in self.scores:
            self.scores[course] += score
        else:
            self.scores[course] = score

    def get_total_score(self):
        return sum(self.scores.values())

    def display_scores(self):
        print(f"Student {self.name} ID: {self.id}")
        for course, score in self.scores.items():
            print(f"{course}: {score}")


def main():
    students = []
    
    while True:
        print("\nOptions:")
        print("1. Add student")
        print("2. View student scores")
        print("3. Exit")

        choice = input("Enter your choice (1/2/3): ")
        
        if choice == "1":
            id = int(input("Enter student ID: "))
            name = input("Enter student name: ")
            new_student = Student(id, name)
            students.append(new_student)

        elif choice == "2":
            for i, student in enumerate(students):
                print(f"{i + 1}. {student.name} - ID: {student.id}")
            selected_id = int(input("Select a student to view their scores: "))
            if selected_id <= len(students):
                students[selected_id - 1].display_scores()

        elif choice == "3":
            break

        else:
            print("Invalid choice. Please try again.")


if __name__ == "__main__":
    main()

这个程序定义了一个`Student`类用于存储学生信息，包含添加分数、获取总分和显示分数的方法。`main`函数则处理用户的交互，如添加新学生、查看成绩等。

要运行此代码，请将其复制到一个名为`student_management.py`的文件中，然后在命令行环境下执行`python student_management.py`。
