I'm trying to make a pong game in pygame , but i can't figure out how to but a ball circle , which i can create with pygame.draw.circle into a pygame.Rect object so i can use the colliderect function and manipulate the ball's position. For example, with rectangles, i can do something like this :

rect = pygame.Rect(255, 255, 100, 100) 
pygame.draw.rect(screen, yellow, rect) 

and then when i change the pygame.Rect object position , the drawing primitives position also changes. How can the same effect be achieved when i want to draw a circle, instead of a rectangle? Thank you.
