I wrote the below code

    if ((not sys.platform.startswith('win32')) or (sys.version_info[:2] < (3, 6))):
        return
    if (not hasattr(stream, 'buffer')):
        return
    buffered = hasattr(stream.buffer, 'raw')
    raw_stdout = (stream.buffer.raw if buffered else stream.buffer)
    if (not isinstance(raw_stdout, io._WindowsConsoleIO)):
        return
    def _reopen_stdio(f, mode):
        if ((not buffered) and (mode[0] == 'w')):
            buffering = 0
        else:
            buffering = (-1)
        return io.TextIOWrapper(open(os.dup(f.fileno()), mode, buffering), f.encoding, f.errors, f.newlines, f.line_buffering)
    sys.__stdin__ = sys.stdin = _reopen_stdio(sys.stdin, 'rb')
    sys.__stdout__ = sys.stdout = _reopen_stdio(sys.stdout, 'wb')
    sys.__stderr__ = sys.stderr = _reopen_stdio(sys.stderr, 'wb')

What's a good function header?

Here's a good function header?
