我已经添加了完整的错误消息以响应用户，但是我有一个由多数代码组成的帖子，因此需要进一步的文本以允许进行编辑。
对于open()函数，请在模式字符串中使用U。
我改变你的open()电话使用Universal Newline Support。它去...
with open(fname, 'r', newline='\r\n') as f:
with open(fname, 'rU') as f:
这解决了我测试中的问题。

本PEP讨论了Python可以在文件上支持I / O的方式，该文件的换行格式不是平台上的本机格式，因此每个平台上的Python都可以使用CR（Macintosh），LF（Unix）读取和导入文件）或CR LF（Windows）行结尾。
