[Tutor] Livewires

[Tonu Mikk]

Hi Sacha,  I am very much a beginner to Python myself, but I tried my 
hand on the Livewires modules.  Here is how I solved the challenge. 

from livewires import *
begin_graphics()
allow_moveables()
x=0
y=0
c = circle(x, y,5)
while x < 640:
    x=x+5
    y=y+3.822
    move_to (c, x, y)
    time.sleep(0.1)
