How to get every value of a key of a JSON file with multiple dicts? I want to extract every value of "username" key.

data.json

{
    "1476439722046238725": {
        "tweet_id": "1476439722046238725",
        "username": "elonmusk",

    },
    "1476437555717541893": {
        "tweet_id": "1476437555717541893",
        "username": "billgate",
    },
    "1476437555717541893": {
        "tweet_id": "1476437555717541893",
        "username": "jeffbezos",

This is what my code so far but it gave me this error KeyError: 'username'.

main.py

import json
with open("data.json", "r") as f:
    data = json.load(f)

print(data["username"])

You need to enumerate through the outer dictionary.

import json
with open("data.json", "r") as f:
    data = json.load(f)

for val in data.values():
    print( val['username'] )
