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

from itertools import combinations

a=['I1','I2','I3','I4','I5']

list(combinations(a,2))

The output will be:

[('I1', 'I2'),
 ('I1', 'I3'),
 ('I1', 'I4'),
 ('I1', 'I5'),
 ('I2', 'I3'),
 ('I2', 'I4'),
 ('I2', 'I5'),
 ('I3', 'I4'),
 ('I3', 'I5'),
 ('I4', 'I5')]
