同学，您好，看同学的报错情况，

我猜测同学的txt文档最后可能存在空行之后在空格的情况，同学可删除之前的考试成绩.txt文档，重新创建个考试成绩.txt文档，复制粘贴下列数据到考试成绩.txt,粘贴完成之后，直接关闭该文档，注意：粘贴时看光标是否自动定位在文档开头，粘贴完成直接关闭文档。

621,赵芳芳,2-1,71,62,80
622,徐丽丽,2-2,78,95,69
623,张倩,2-2,96,88,89
624,胡倩倩,2-2,98,99,100
625,赵晓婷,2-3,91,87,89
626,李伟,2-3,53,68,67
627,王秀英,2-4,86,87,87
628,李静,2-4,65,68,74
629,郭楠楠,2-4,78,81,94
630,邓逸凡,2-4,70,66,61

同学，您好，我们测试了下您的代码，没有发现问题，同学可print(temp)，将捕获异常的try:，except Exception as e:，finally:去掉，看看控制台会报什么错误。将报错信息截图，贴图贴出来。
