Newbie question involving buffered input

That makes sense I suppose - why is there a stdin.flush() method then?

You cannot flush input.  The flush method only relates to output.  The
*other* side of the file has to flush *its* output in order for you to
see it as input.

On Linux, the termios module provides a way to tell the system not to do
any buffering on a file descriptor.  pywin32 may expose equivalent
functionality for Windows.
