Names and codes

[janek30]

I have a dictionary to people's names and codes,like this:

  Names_and_codes = {"Emily":30623,
                  'Ethan':21298,
                  "Chloe":40145,
                  "Olivia":61834,
                  "Daniel":51398,
                  "William":82523,
                  "Emma":70623}

 

And I have a list of codes,like this :

codes =[[30623 ,70623],
        [61834 ,40145],
        [51398, 21298],
        [21298 ,40145],
        [61834 ,82523],
        [21298, 82523]] 

The first number in list is the parents number and the second children's number...I need to find my parents and their kids,And put them in a new dictionary... like this:

 new_dic = {'Ethan': {'Chloe', 'William'},
'Olivia': {'Chloe', '"William'}, 
'Daniel': {'Ethan'}, 
'Emily': {'Emma'}}
