Python pyqt5功能实现
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1入OS模块，用于导人导出路径文件信息
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
基于new bing部分指引作答：
运行结果：
以下是使用Python和PyQt5实现上述功能的示例代码：

你是要做带界面的还是控制台的就可以，可以参考我之前做的：
python实现学生成绩管理程序，包含各科成绩的录入，计算各个学生的总分和平均分，统计各个科目的最高分、最低分和平均分。

- 除此之外, 这篇博客: python小白自学基础知识（二）附加(人狗大战游戏)中的 根据函数和面向对象（类）的知识，概括为一个总的例子（该例子我在其他的文章中见过），作为上课的内容，老师要求实现人狗大战游戏代码编写，内容中包含：人初始化的金钱额度，金钱用于买枪，枪对狗的伤害，以及狗的血量，最后是人在多少次把狗打死（其中没有涉及到人打狗的同时，狗也在咬人，但是却定义了狗对人的伤害，有兴趣的朋友可以继续把游戏做下去） 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
