Here's an example from Python 2.2.
last, rand = 1, random.random() # initialize candidate elements
while rand > 0.1: # threshhold terminator
print '*', # display the rejection
if abs(last-rand) >= 0.4: # accept the number
last = rand # update prior value
yield rand # return AT THIS POINT
rand = random.random() # new candidate
yield rand # return the final small element
for num in randomwalk_generator():
Ruby also has a yield keyword and I think it can be used in this way but
is more general than Python's.
