plus Python, unlike some other languages, allows us to return multiple
values, either as a collection or as an implied-tuple:

def function_list():
    a_list = [ i for i in range( 9 ) ]
    return a_list

def function_multiples():
    a = 1
    b = 2
    c = 3
    return a, b, c

thus:

x, y, z = function_multiples()
