简易自动生成小学生作业【开源】
自动生成三位数以内的小学生加减法作业，并生成A4大小的PDF文件便于打印，效果如图所示：
便捷使用
- 下载已经编译好的程序 点我直达下载
- 解压文件，注意解压出来的四个文件必须在同一文件夹下
- 运行
homeworkProduce.exe，第一次运行会自动下载Chrome driver
- 根据提示填入需要生成多少张作业，每张试卷口算练习题数量，竖式计算题数量，然后回车
- 在
output文件夹下会生成指定数量张的作业
实现思路
- 作业模板基于
HTML+CSS，使用jinja2模板引擎动态渲染数据传入HTML
- 基于
Chrome headless的Api将HTML打印成PDF，这里使用Pyppeteer
自行编译
代码写得很烂
