A quick test

Every third item must be Fizz or FizzBuzz, and every fifth item must be Buzz or FizzBuzz:

>>> EVERY_THIRD = slice(2, None, 3)
>>> EVERY_FIFTH = slice(4, None, 5)

>>> all(item.startswith('Fizz') for item in fizz_buzz[EVERY_THIRD])
True
>>> all(item.endswith('Buzz') for item in fizz_buzz[EVERY_FIFTH])
True
