用python编写一个程序，其中包括一个菜单和一个多选列表框。菜单应该包含两个选项：添加学生和删除学生。当用户选择添加学生选项时，程序应该弹出一个对话框，要求用户输入学生的姓名、年龄和成绩。当用户选择删除学生选项时，程序应该从列表框中删除当前选定的学生。同时，当用户在列表框中选择一个学生时，程序应该显示该学生的详细信息

好的，以下是Python代码实现：

import tkinter as tk
from tkinter import messagebox

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

    def __str__(self):
        return f"{self.name} ({self.age} years old) - Score: {self.score}"

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

    def add_student(self, name, age, score):
        student = Student(name, age, score)
        self.students.append(student)

    def remove_student(self, index):

这个程序包括一个 `Student` 类，用于表示学生的姓名、年龄和成绩，以及一个 `StudentManagementSystem` 类，用于管理学生。GUI 部分使用 `tkinter` 库，包括一个菜单和一个多选列表框。当用户选择添加学生选项时，程序弹出一个对话框，要求用户输入学生的姓名、年龄和成绩。当用户选择删除学生选项时，程序从列表框中删除当前选定的学生。同时，当用户在列表框中选择一个学生时，程序显示该学生的详细信息。
