Program to move a dot towards a circle center

[plumberpy]

Here is a very basic script using pygame:

from pygame import display, QUIT, event, draw, time 
SCREEN = display.set_mode ((500, 500))

dot_x_position = 30
while True :
	for user_input_event in event.get () :
		if user_input_event.type ==  QUIT :
			exit ()
	SCREEN.fill ((0, 0, 0))
	draw.circle (SCREEN, (200, 0, 0), (249, 249), 220, 4)
	draw.circle (SCREEN, (0, 0, 200), (dot_x_position, 249), 20)
	if dot_x_position < 249 :
		dot_x_position += 1
	time.Clock ().tick (100)
	display.update ()

Many thanks! I have tried it and it is what I want to start with. I will add to it to do what I have in mind.

Much appreciated.
