# iterate over random numbers from 1 to 10; use 0 as a sentinel to
stop the iteration
for n in iter(lambda:random.randrange(10), 0):
print n
More generally, iter(callable, sentinel) is just a convenience
function for the following generator:
def iter(callable, sentinel):
while True:
c = callable()
if c == sentinel: break
yield c
