#56475 — Pygame with python 3.3.2

From pygame tutorials i copied this example:
import pygame
 
class spritesheet(object):
    def __init__(self, filename):
        try:
            self.sheet = pygame.image.load(filename).convert()
        except pygame.error, message:
            print('Unable to load spritesheet image:', filename)
            raise SystemExit, message
    # Load a specific image from a specific rectangle
    def image_at(self, rectangle, colorkey = None):
        "Loads image from x,y,x+offset,y+offset"
        rect = pygame.Rect(rectangle)
        image = pygame.Surface(rect.size).convert()
        image.blit(self.sheet, (0, 0), rect)
        if colorkey is not None:
            if colorkey is -1:
                colorkey = image.get_at((0,0))
            image.set_colorkey(colorkey, pygame.RLEACCEL)
        return image
    # Load a whole bunch of images and return them as a list
    def images_at(self, rects, colorkey = None):
        "Loads multiple images, supply a list of coordinates" 
        return [self.image_at(rect, colorkey) for rect in rects]
    # Load a whole strip of images
    def load_strip(self, rect, image_count, colorkey = None):
        "Loads a strip of images and returns them as a list"
        tups = [(rect[0]+rect[2]*x, rect[1], rect[2], rect[3])
                for x in range(image_count)]
        return self.images_at(tups, colorkey)

When ever i run it i get syntax error on this line except pygame.error, message:
There are no example to show what happens, because, this doesent even work, untile the error is fixed. My guess is, that this has something to do with the python versions. But im not very familiar with the changes so i dont know how to fix it.

 From http://docs.python.org/3.0/whatsnew/3.0.html "Change from except 
exc, var to except exc as var. See PEP 3110."  You might also like to
