pygame

Hi there everyone!
I'm making a Pygame of, basically, "Breakout".
I'm using collisions, and want a simple way to have different bounce effects of the different sides of one rectangle.
What I currently have for the ball-to-bat collision is this:
"dot" = ball; "bat" = bat; so you all understand.

if dot.rect.colliderect(bat.rect):<br>
 dot.dy *= -1

I'd like something that interacts with each side, so could reverse the self.dx value of the ball when it hits the side of the bat, and only reversing the self.dy value when it strikes the top.

Thanks!!! :D
