Like:
[{k:[sub1[v] for v in vs] for k, vs in sub2.items()}for sub1, sub2 in zip(list_1, list_2)]this produces - with your sample input:
>>> list_1 = [['a','b','c'], ['d','e','f']]>>> list_2 = [{'key_11': [0,2] , 'key_12': [0]}, {'key_21': [2,0], 'key_22': [1]}]>>> [{k:[sub1[v] for v in vs] for k, vs in sub2.items()}... for sub1, sub2 in zip(list_1, list_2)]Content Under CC-BY-SA license python - How to do multiple arguments to map function where …
>>> list(map(pow, range(10), repeat(2))) [0, 1, 4, 9, 16, 25, 36, 49, 64, 81] This makes for a nice lazy-functional-language-y solution that's also perfectly readable in Python-iterator terms.
