基本信息管理模块的主要功能有学生信息的添加、删除、修改、显示和学生数据的导入导出，学生成绩管理模块的主要功能有统计课程最高分、最低分和平均分。要求按照面向对象思维进行编写，按照以下模式完成： 1、设计一个学生类，包含学号、姓名、语文成绩、数学成绩和英语成绩等数据成员。 2、引入OS模块，用于导入导出路径文件信息 3、设计一个学生管理类，用于定义各个模块的具体功能函数。 4、设计一个主菜单，两个子菜单，分别管理学生基本信息和学生成绩信息

好的，根据您的要求，我可以给出一个简单的面向对象实现代码示例，供您参考。

if __name__ == '__main__':
    menu = Menu()
    menu.run()

以上代码实现了一个简单的学生基本信息管理和学生成绩管理程序，具体操作流程如下：

1. 运行程序，进入主菜单；
2. 选择子菜单“学生基本信息管理”；
3. 在子菜单中选择添加、删除、修改、显示、导入或导出学生信息；
4. 返回上级菜单；
5. 选择子菜单“学生成绩管理”；
6. 在子菜单中选择统计语文、数学或英语的最高分、最低分或平均分；
7. 返回上级菜单；
8. 退出程序。

希望对您有所帮助！
