Names and codes

[janek30]

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

1 2 3 4 5 6 7 8 9

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 :

1 2 3 4 5 6

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:

1 2 3 4 5 6

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

So if you show what you've done so far, in addition to entering the lists,
I'll (or any of the other moderators) will be glad to help finish it

Actually, it's a little longer homework...,First, I had to get the data from the file, I got it done......
CODE:
   

1 2 3 4 5 6 7 8 9 10 11 12 13 14

def Children_and_parents(f1, f2):     f = open(f2, encoding = "UTF-8")     ff = open(f1, encoding = "UTF-8")      m = {}     s = []     new_dic = "?????"     for i in f:         d = i.split()         for osa in d:             m[" ".join(d[1:])]= d[0]             for ri in ff:                 os = ri.split()                 s.append(os)     return(new_dic)

But now I'm stuck, How i find parents and their children,and put them in a new dictionary(new_dic)

Start with a function that takes the parent's name/code, and returns that parent's children. That should be a small stepping stone to helping you solve this.
