How to get the rect() of a dynamic circle

I am trying to get the rect of the circle in the draw method but Pygame gives an error everytime I call the get_rect() method on my Alien instance.

All drawing functions of the pygame.draw module return a rectangle representing the bounding area of changed pixels.

Update your draw() method

    return pygame.draw.circle(screen, colour, (self.x, self.y), self.size)

to return a pygame.Rect object which you could use e.g. for collision detection.
