Convert dict from list - HELP! PLEASE!

[cherry_cherry]

Hi everyone,
I'm trying to transfer a list to a dictionnary and sort a new dict with key, but it's not success.
This is a list I need transfer:

[
{"numero":"20202020","name" : "Durand", "first":"Martin", "notes":[12,15.5,8,13]},
{"numero":"21212121","name" : "Dupond", "first":"Alain", "notes":[11,9.5,5.5,18]},
{"numero":"21202120","name" : "Bru", "first":"Mélissa", "notes":[11,19.5,15,8]},
{"numero":"20212021","name" :"Bosse", "first":"Mélissa", "notes":[13,19.5,15,8]},
{"numero":"21202120","name" : "Allard", "first":"Chloé", "notes":[11,9.5,2,8]},
{"numero":"20202020","name" : "Durand", "first":"Martin", "notes":[12,15.5,8,13]}
]

And this is a format of dict I need shows:

{"20202020":{"name" : "Durand", "first":"Martin", "notes":[12,15.5,8,13]},
"21212121":{"name" : "Dupond", "first":"Alain", "notes":[11,9.5,5.5,18]},
...
}

So, with this format: key is numero and value is another.

I REALLY NEED YOU HELP!!!! THANK YOU SO MUCH!!!

What have you tried so far?

Hi,
Actually, It's part of my topic: I consider the list under condition that if value of numero isn't duplicated, a new dict will be issued. And I tried but I know it's not right and not okay.I just started learning Python so this is totally I can write now. And thank for your reply!

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

import json   def check(seq):     new_dict = {}       i = 0     j = 1     for i in seq:         for j in seq:             if i['numero'] == j['numero']:                 print("Numero en double!")                 print("----> ", i['numero'])                 return ("Fichier non utilisable!")             else:                 a = str(i['name'])                 new_dict.update({i["numero"]: a})     return new_dict
