chaoxing = ChaoXing(user="", password="")在这里输入账号密码然后运行就可以啦.
嗯嗯，这部试过了，会列出课程列表，有的课程可以正常显示作业，但是有的课程提示这个
Empty DataFrame
Columns: []
Index: []
请输入你想下载文件的序号: BlueAir 发表于 2022-5-17 11:07
好的，找到了，谢谢你，还有问题就是 有的课程无法获取作业列表，有的获取到作业列表，但是下下载报 ...
后来又试了一下，应该是只能识别doc，和txt 类别的，视频和图片识别不了:loveliness::loveliness::loveliness: 多给点免费的评分吧，大佬们:lol 好啊，有了这个再也不用等了。 看看怎么样 这是个好东西，收藏备用 看看，学习一下 厉害了，能推荐给同学吗？ 看看谢谢楼主分享 ModuleNotFoundError: No module named 'requests'
这是用什么版本写的？运行时出现了上面的代码。 666 虽然已经用不到了
