Question

Hi how can i get a mapped list to print all possible combinations

say the dict mapping is = {1:[a,b],2:[c,d]……

so with the list [1,2] and the sample mapping above I would like to print out all possible combinations of the pairs a,d against c,d into a list

Answer 1

from itertools import product

mapping = {1:['a','b'], 2:['c','d']}
data = [1, 2]
for combo in product(*(mapping[d] for d in data)):
    print combo

results in

('a', 'c')
('a', 'd')
('b', 'c')
('b', 'd')

Edit it sounds like what you actually want is

strings = [''.join(combo) for combo in product(*(mapping[d] for d in data))]

which gives strings == ['ac', 'ad', 'bc', 'bd'].
