Serhiy Storchaka added the comment: codecs.open() works with bytes-to-bytes codecs.
>>> f = codecs.open('test1', 'w', encoding='hex_codec') >>> f.write(b'hello') >>> f.close() >>> open('test1', 'rb').read() b'68656c6c6f' In additional the interface of StreamReaderWriter is not fully compatible with the interface of io classes. This would be compatible-breaking change. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29783> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
