sys.stdin.flush() doesn’t seem to flush stdin, so I am using the termios
module.
You're aware that a stdio flush and a termios flush operate on two totally
unrelated buffers?
while True:
input = sys.stdin.readline()
# do some parsing
…
sys.stdout.write(parsed_data)
time.sleep(3)
termios.tcflush(sys.stdin, termios.TCIOFLUSH)
I am receiving this exception
termios.error: (25, 'Inappropriate ioctl for device')
That is because stdin is attached to the pipe from netcat. A pipe is not a
terminal.
I will be using this script on Unix based systems and I wondered what
approach I could use
to flush stdin?
Like Chris, I think you need to explain why you even want to flush stdin.
There's probably something better you can do.

I strongly suspect so. Practically everyone on sci.physics has a theory that
is far superior to special relativity, general relativity, quantum mechanics
*and* the standard model. Around here, it's only a small clique of arrogant
young members of the physics establishment who fail to recognize these
revolutionary theories. I'd explain why, but I have to go finish designing
my faster-than-light vacuum energy perpetual motion telekinetic
aether-powered time machine. - John Baez
