Serhiy Storchaka added the comment: https://docs.python.org/3/library/io.html#io.TextIOBase.buffer """buffer The underlying binary buffer (a BufferedIOBase instance) that TextIOBase deals with.

It is common to replace standard streams with StringIO. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue21995> _______________________________________
