Linux : Python : Clear Input Buffer Before Raw_input()

I have looked at a few thread about this, but it doesn't seem to solve my problem. I am running linux and when I use raw_input(), with a pause between each, it will take the data t

Solution 1:

For unix you can use termios.tcflush

from termios import tcflush, TCIFLUSH
import time,sys

a = raw_input("first input ")
b = raw_input("second input ")

time.sleep(5)
tcflush(sys.stdin, TCIFLUSH)

a = raw_input("third input ")
b = raw_input("fourth input ")

~$ python foo.py 
first input1
second input23333
third input3
fourth input4

termios.tcflush(fd, queue)

Discard queued data on file descriptor fd. The queue selector specifies which queue: TCIFLUSH for the input queue, TCOFLUSH for the output queue, or TCIOFLUSH for both queues.

Solution 2:

Use keypress getch class of tty (linux) and msvcrt (windows) and use sys.stdout.flush() function to flush the buffer
