【小学生作业自动生成】自动生成小学加减法作业

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

• 支持Python3.6、Python3.7、Python3.8、Python3.9、注意WIn7不支持Python3.8以上

• pip install jinja2
pip install pyppeteer

代码写得很烂
