首先需要登录创建 session 文件

>>> from pysjtu import Session
>>> sess = Session(username="blabla", password="blabla")
>>> sess.dump("session")

然后创建 courses 文件配置选课

expect<>ok(请求成功匹配的字符串)
interval<>0.5(每轮循环之间的间隔秒数)
(课程显示名 提示作用 可以乱写)<>(从浏览器F12里找到选课的post请求，然后右键复制>复制为cURL请求，直接贴)
基电<>curl 'https://i.sjtu.edu.cn/......' -H blablabla ...

然后直接跑 elect_course.py
