command CHOICE in DOS batch replacement/reproduction in python

I want to reproduce the behavior of the command CHOICE in DOS batch but with python.

raw_input requires the user to type whatever then press the ENTER/RETURN key. What I really want is for the user to press a single key and the script to continue from there.

For Unix, it uses sys, tty, termios modules.

import sys, tty, termios
fd = sys.stdin.fileno()
old_settings = termios.tcgetattr(fd)
tty.setraw(sys.stdin.fileno())
ch = sys.stdin.read(1)

For Windows, it uses msvcrt module.

import msvcrt
ch = msvcrt.getch()
