Good point.
This example intrigues me. When I saw the first couple of lines,
I expected
def fib():
generation, parent_rabbits, baby_rabbits = 1, 1, 1
while True:
yield generation, baby_rabbits
generation += 1
parent_rabbits, baby_rabbits = \
baby_rabbits, parent_rabbits + baby_rabbits
for pair in fib():
if pair[0] > 100:
break
print "Generation %d has %d (baby) rabbits." % pair
as more appealing to non-Pythoneers. I'm still suspicious about
how they're going to react to itertools.islice(). Now, though,
I've begun to question my own sense of style ...
