Example

Loop over range(20), apply the fibo() function and then, on top of it, apply the fizzbuzz() function, finally, apply print():

from loop import loop_over


def fizzbuzz(x):
    rules = {3: 'fizz', 5: 'buzz'}.items()
    res = ''.join(word for div, word in rules if x%div == 0)
    return res if res else x


def fibo(x):
    a, b = 1, 1
    for _ in range(1, x):
        a, b = b, a + b
    return b


loop_over(range(20)).map(fibo).map(fizzbuzz).map(print).exhaust()

Will produce the following output:

1

buzz
