permutates all elements in list values of a dictionary to return a dictionary with the same keys but single values

dictionary_values_permutations.py

import itertools

my_dict = {'A':['D','E'],'B':['F','G','H'],'C':['I','J']}
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'},
# ...
