I missed that the file's attribute newlines can be None if no line separators were read. It can also be a tuple if mixed newlines are used. I think that eol_convention should be set to the default value os.linesep in these cases. I am currently not able to test this since IDLE does not work on my computer after upgrading to Ubuntu 20.04. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41373> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
