無駄にitertoolsを駆使したFizzBuzz(Python3では動きません)

# 無駄にitertoolsを駆使したFizzBuzz

from itertools import repeat, ifilterfalse, starmap, count

N = 31
LEN = range(1, N)
FIZZ, BUZZ = map(repeat, ("Fizz", "Buzz"))

fizz, buzz = (
        map(list,
            starmap(ifilterfalse,
                [(lambda i: i%3, LEN), (lambda i: i%5, LEN)])))

fizz, buzz = starmap(map,
        [(lambda i: i in fizz, LEN), (lambda i: i in buzz, LEN)])

fizz, buzz = starmap(zip,
        [(fizz, FIZZ), (buzz, BUZZ)])

fizz, buzz = starmap(starmap,
        [(lambda x, y: x * y, fizz), (lambda x, y: x * y, buzz)])

fizzbuzz = starmap(lambda x, y: x + y, zip(fizz, buzz))

print(' '.join([(item or str(i)) for i, item in zip(count(1), fizzbuzz)]))

Pythonならホントはワンライナーで書けるけど敢えてitertools縛りで。
