getch() in Python - get a single character from keyboard

Today I needed to write a Python code for 'Press any key to continue' feature. First I wrote the code: raw_input("Press Any Key to Continue: ")
But actually it's not any key, you have to press enter followed by any key (or just enter). Then I started searching Google, came across several links, tried some of those and finally got something which is very close to what I need and modified the code to fit into my need. Here is the link that was almost exactly what I needed: http://pyfaq.infogami.com/how-do-i-get-a-single-keypress-at-a-time

Here is my getch function in Python:

import sys    
import termios
import fcntl

def myGetch():
    fd = sys.stdin.fileno()

    oldterm = termios.tcgetattr(fd)
    newattr = termios.tcgetattr(fd)
    newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
    termios.tcsetattr(fd, termios.TCSANOW, newattr)

    oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
    fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

    try:        
        while 1:            
            try:
                c = sys.stdin.read(1)
                break
            except IOError: pass
    finally:
        termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
        fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

And this one is also interesting but I couldn't make it work: getch()-like unbuffered character reading from stdin on both Windows and Unix (Python)
