This is not about complex behaviour but simply correct behaviour. For the record, universal newlines are enabled by default in Python 3: >>> with open("foo", "wb") as f: f.write(b"a\r\nb\rc\n") ... 7 >>> with open("foo", "r") as f: print(list(f)) ... ['a\n', 'b\n', 'c\n'] Regards Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
