python超星尔雅学习通利用selenium一键建题库和一键做题
前言
本文内代码适用的作业
-
多章节
-
大量单选，多选和判断题
-
作业内题目乱序
-
题目内选项乱序
-
没有主观题
实现过程主要分为两块，一块是登录其他已经完成作业的账号，爬取其所有已完成作业的题目与答案，并保存为txt文件；另一块是登录自己的账号，爬取题目信息与txt内题库进行比对，实现一键自动完成作业。
功能方面同样可以使用requests库达到目的，相关原理与 https://blog.csdn.net/m0_47926132/article/details/106957460?utm_source=app
内容同理。

注意事项（重要）
- 代码复制即可用
- 在模拟登录完成后需要手动将页面切换至需要爬取题库&一键做题的课程作业页面，然后在控制台里按下回车
- 为避免由于个人操作失误或代码运行错误造成不可挽回的错误，我在代码提交每章作业部分设置了手动操作部分，为了操作者能确保代码完成了所有题目。
