FIzzbuzz with Dynamic Inputs

fizzbuzz.py

# Creates a functions that inputs the number of arrays, 
# and a dict of number to string pairs.
#
# This is my attempt to pythonise the fizzbuzz algorithm 
# such that it is dynamic, and you can put as many terms
# as you like with regular intervals.
# The default settings work such that the output would 
# be a dict which the keys are initialised from 1 to 100,
# and the values would have 'fizz' in keys that have 
# multiples of 3, and 'buzz' in keys that have multiples 
# of 5.

def fizzbuzz(array_no=100, fizzbuzz_dict={3: 'fizz', 5: 'buzz'}):
    # Creates a list from 1 to array_no
    no_array = list(range(1, array_no+1))
    # Creates a lambda formula that creates a list with multiples
    formula = lambda a, dict_a: (([''] * (a-1) + [dict_a]) * \
                                 ((array_no + a)//a))[:array_no]
    # Maps the fizzbuzz_dict to the formula function
    fizzbuzz_dict2 = map(lambda x: formula(x, fizzbuzz_dict[x]), fizzbuzz_dict)
    # Joins the fizzbuzz to a single list
    fizzbuzz_dict3 = list(map(lambda x: ''.join(x), zip(*fizzbuzz_dict2)))
    # Returns a dict with the number list and the fizzbuzz results
    return dict(zip(no_array, fizzbuzz_dict3))
