That translates fairly well into Python, with its set type and list/set/dict comprehensions.

    def setrange(first, next, last):
        return set(range(first, last+1, next-first))
    
    fizz = setrange(3, 6, 100)
    buzz = setrange(5, 10, 100)
    fizzbuzz = fizz & buzz
    fizz -= fizzbuzz
    buzz -= fizzbuzz
    num = setrange(1, 2, 100) - fizz - buzz - fizzbuzz
    line_map = dict({n: "Fizz" for n in fizz}.items() +
        {n: "Buzz" for n in buzz}.items() +
        {n: "FizzBuzz" for n in fizzbuzz}.items() +
        {n: n for n in num}.items())
    for i in range(1, 100+1):
        print(line_map[i])

Some SETL features Python lacks:

• No ellipsis notation for ranges; must use the "range" function and add one to the maximum value, or define a custom "setrange" function

• Can't concatenate dictionaries; must concatenate their "items" lists and convert back to a dictionary

• No consistent map-lookup notation; collections are indexed with brackets, but functions are called with parentheses
