使用图形界面显示,选用list、tuple、dictionary或map等数据结构,操作数据库存储X个学生的三门课的成绩(机器学习、Python程序设计、研究生英语),并实现以下功能:
1.添加学生信息
2.修改学生信息
3.删除学生
4.添加学生的成绩
5.修改学生成绩
6.按姓名或者学号查找学生,显示学生信息及三门课的成绩,以及排名
7.学生成绩统计(每门课的平均分、最高分、最低分)
# 打开数据库连接 连接测试
db = pymysql.connect("localhost", "root", "root", "student")
分别表示 主机名:localhost,用户名:root,密码:root,数据库名:student
管理员操作界面,拥有增删改查功能,甚至拥有排序功能φ(>ω<*) ,快点击标签栏试试
