01 what the model was asked

Create fizzbuzz.py with exactly one function:

fizzbuzz(n: int) -> list[str]
    Return a list for the numbers 1 through n inclusive: "FizzBuzz" for multiples of both 3 and 5, "Fizz" for multiples of 3, "Buzz" for multiples of 5, otherwise the number as a string. fizzbuzz(0) returns an empty list.

Use only the Python standard library.
