The following code listing is for a cross platform method for grabbing the screen in Python. It uses PIL on Windows, and ImageMagick on other platforms.

import PIL
import os
import platform

def grab_screen(fname):
    if platform.system() == 'Windows':
        PIL.ImageGrab.grab().save(fname, "JPEG")
    else:
        cmd = "import -window root %s" % fname
        os.system(cmd)
