-------------------------------------------------------------------------------- 1 | # student-assigment 2 | Python课程作业，win32软件 3 | 4 | 其中一个是基于tkinter和MySQL实现的学生管理系统，因为只是一个日常作业，所以没有花费太多时间仅实现了基本的增删改查功能。 5 | 6 | 另一个是使用Tkinter实现的简单计算器，可以处理带括号的长算式。 7 | 8 | 还有一个是使用PyQT5开发的文件加密软件。 9 | 10 | [学神信息管理](./student) 11 | 12 | [计算器](./calculator) 13 | 14 | [文件加密](./file_encryption) 15 | 16 | ## 开发环境 17 | 18 | PyCharm 19 | 20 | python == 3.7 21 | 22 | 打包工具： PyInstaller == 3.6 23 | 24 | ## 部署说明 25 | 26 | ### 学生管理系统 27 | 28 | 数据使用MySQL存储，请先使用**student.sql**建立数据库，然后修改**config.ini**中的数据库连接信息，之后再将项目导入PyCharm或者其他IDE，程序入口文件为**login.py**。 29 | 30 | dist目录中有已经打包好的exe文件，修改**config.ini**中的数据库配置后理论上可以运行。 31 | 32 | 如果需要修改程序后重新打包成exe文件，可使用PyInstaller或者其他打包工具，打包后记得**将config.ini和welcome.gif复制到exe文件所在目录，否则无法运行**（具体视修改情况）。 33 | 34 | 学生管理打包命令： 35 | 36 | ```cmd 37 | pyinstaller -F -w login.py -p database.py -p gui.py -p view.py 38 | ``` 39 | 40 | --------- 41 | 42 | ### 计算器 43 | 44 | 计算器入口文件为**main.py**，view.py只是一个界面，无功能 45 | 46 | 计算器打包命令： 47 | 48 | ```cmd 49 | pyinstaller -F -w main.py -p view.py 50 | ``` 51 | 52
