For example, in Python, I'd naturally generate a list of random points
asl = [(randint(0,100), randint(0,200)) for n in range(200)]
Then, to draw radius-10 circles at each point,
for pt in l:
dc.DrawCircle(pt, 10)Compare this to the non-tuple version:
for n in xrange(200):
x, y = randint(0,100), randint(0,200)
dc.DrawCircle(x, y, 10)
