培训管理系统拟实现功能
作者：天使Python
1 录入学生信息
2 查找学生信息
3 删除学生信息
4 修改学生信息
5 排序
6 统计学生总人数
7 显示所有学生信息
0 退出系统
由于程序较为简单，不做详细介绍

生成exe文件
若电脑未安装PyInstaller模块
在命令提示符窗口中输入"pip install pyinstaller"
安装模块后，在命令提示符模块中输入"pyinstaller --version"查看模块版本，验证模块是否正确安装
在命令提示符模块中输入"pyinstaller -F 要打包的py文件位置，例如:
pyinstaller -F C:\Users\ZLH\dist\student.py
