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

If you want to keep the key:value in the permutations you can use:

import itertools
keys, values = zip(*my_dict.items())
permutations_dicts = [dict(zip(keys, v)) for v in itertools.product(*values)]

this will provide you a list of dicts with the permutations:

print(permutations_dicts)
[{'A':'D', 'B':'F', 'C':'I'}, 
 {'A':'D', 'B':'F', 'C':'J'},
 ...
 ]

disclaimer not exactly what the OP was asking, but google send me here looking for that.
