Looping a script

I am a newbie in programming and I started working with Sikuli open source package and uses Python language.

I would like my image match finding script posted below to repeat from the beginning once it reaches the end without user intervention. Here is what I have and the last line I commented, but its empty as far as repeating the script line codes?

# functions to be used in different situations
def captureSymbol(i = 0):
r = other[i]
x = r.x + sbMarginLeftRight
w = r.w - 2 * sbMarginLeftRight
y = r.y + sbMarginTopBottom
h = r.h - 2 * sbMarginTopBottom
r = Region(x, y, w, h)

return capture(r)

def captureLeftSmallest():
# capture the image to search
# we have to try to get the smallest capture possible
# since the probe and the target have different positions
# this can be set fixed, if it is always the same
# find the bottom of image
greyBelow = "1354183324452-1.png"
g = left.find(greyBelow)
#g.highlight(1)
while True:
g1 = g.above(sbHeight-g.y)
g1.x -= 4; g1.w += 8
g1 = g1.exists(greyBelow)
if not g1: break
g = g1
#g.highlight(1)
b = g.y

# find the left side of image
greyLeft = "1354183672313-1.png"
g = left.find(greyLeft)
#g.highlight(1)
while True:
g1 = g.right(left.w - g.x)
g1.y -= 4; g1.h += 8
g1 = g1.exists(greyLeft)
if not g1: break
g = g1
#g.highlight(1)
l = g.x + g.w

# define the smallest possible image region
symbol = Region(l, b - 60, 50, 60)
#symbol.highlight(3)
return capture(symbol)

# find the cell containing the symbol
match = None
for i in range(start, len(other)):
if other[i].exists(imgSymbol, 0):
match = other[i]
break
if not match: return None

return match
