I have two list:

lists = [\'a\',\'b\',\'c\',\'d\',\'e\']
keys = [18,18,3,4,5]

what I want is a dictionary like this:

{18:[\'a\',\'         


        

Answer 1

Upon reading a post suggestion from stackoverflow:

dictionary = {k: [values[i] for i in [j for j, x in enumerate(keys) if x == k]] for k in set(keys)}

I have solved it.
