How to generate all combination from values in dict of lists in Python

Question

I would like to generate all combinations of values which are in lists indexed in a dict:

{\'A\':[\'D\',\'E\'],\'B\':[\'F\',\'G\',\'H\'],\'C\':[\'I\',\'J\']}         


        

Answer 1

import itertools as it

my_dict={'A':['D','E'],'B':['F','G','H'],'C':['I','J']}
allNames = sorted(my_dict)
combinations = it.product(*(my_dict[Name] for Name in allNames))
print(list(combinations))

Which prints:

[('D', 'F', 'I'), ('D', 'F', 'J'), ('D', 'G', 'I'), ('D', 'G', 'J'), ('D', 'H', 'I'), ('D', 'H', 'J'), ('E', 'F', 'I'), ('E', 'F', 'J'), ('E', 'G', 'I'), ('E', 'G', 'J'), ('E', 'H', 'I'), ('E', 'H', 'J')]
