# (0, 0, 255): The color of the ellipse in RGB format, here it represents blue color.
# pygame.Rect(40, 80, 200, 80): The bounding rectangle for the ellipse. 
#                               It defines the position and dimensions of the ellipse.
#                               The parameters represent (left, top, width, height) of the rectangle.
#                               Here, the rectangle is positioned at (40, 80) with a width of 200 pixels
#                               and a height of 80 pixels.
# width=0: The width of the outline of the ellipse. 
#          Setting it to 0 means that the ellipse will be filled with the specified color.
