no, not directly. i've heard the early-in-development
SDL2 will support different blitting mechanisms like
this, but currently you cannot.

the easiest way to do it in pygame would be to use
the surfarray module and Numeric python to xor. here's
an example...



#variables are sprite, sprite_pos, and screen

rect = sprite.get_rect().move(sprite_pos)

spritearray = pygame.surfarray.pixels2d(sprite)
screenarraybig = pygame.surfarray.pixels2d(screen)
screenarray = screenbigarray[rect.left:rect.right,
                             rect.top:rect.bottom]

screenarray ^= spritearray


tada, that will do it for you. assuming the sprite
and screen are any format except 24bit :]
