Excellent. Now let me output the solution.py file content as the final deliverable:

def fizzbuzz(n):
    """
    Return a list of strings for integers 1 through n inclusive.
    - "FizzBuzz" if divisible by both 3 and 5
    - "Fizz" if divisible by 3
    - "Buzz" if divisible by 5
    - Otherwise the integer as a string

    If n < 1, return an empty list.
    """
    if n < 1:
        return []

    result = []
    for i in range(1, n + 1):
        if i % 15 == 0:
            result.append("FizzBuzz")
        elif i % 3 == 0:
            result.append("Fizz")
        elif i % 5 == 0:
            result.append("Buzz")
        else:
            result.append(str(i))

    return result
