This works ONLY on Windows:

import sys
import time
from msvcrt import getch,kbhit

time.sleep(3)
while kbhit(): getch() # consume any pending keypresses
print
input = raw_input('Your input: ')
print 'Your input: ', input

For Unix you could look at the tty/termios modules. This recipe shows 
a portable getch() function:
