On Cygwin the same tests give >>> f = open('/dev/null', 'wb') >>> f.seekable() True >>> f.write(b'abcdefgh') 8 >>> f.tell() 8 >>> f.seek(8) 8 >>> f.tell() 8 I would also try macOS if I could. But yes, I wonder if it's a Linux bug. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34904> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
