Extract data from a JSON file using python - json

Question

Say if I have JSON entry as follows(The JSON file generated by fetching data from a Firebase DB):
[{"goal_savings": 0.0, "social_id": "", "score": 0, "country": "BR", "photo": "http://graph.facebook", "id": "", "plates": 3, "rcu": null, "name": "", "email": ".", "provider": "facebook", "phone": "", "savings": [], "privacyPolicyAccepted": true, "currentRole": "RoleType.PERSONAL", "empty_lives_date": null, "userId": "", "authentication_token": "-------", "onboard_status": "ONBOARDING_WIZARD", "fcmToken": ----------", "level": 1, "dni": "", "social_token": "", "lives": 10, "bills": [{"date": "2020-12-10", "role": "RoleType.PERSONAL", "name": "Supermercado", "category": "feeding", "periodicity": "PeriodicityType.NONE", "value": 100.0"}], "payments": [], "goals": [], "goalTransactions": [], "incomes": [], "achievements": [{"created_at":", "name": ""}]}]
How do I extract the content corresponding to 'value' which is present inside column 'bills' . Any way to do this ?
My python code is as follows. With this I was only able to get data within bills column. But I need only the entry corresponding to 'value' which is present inside bills.
import json
filedata = open('firebase-dataset.json','r')
data = json.load(filedata)
listoffields = [] # To produce it into a list with fields
for dic in data:
try:
listoffields.append(dic['bills']) # only non-essential bill categories.
except KeyError:
pass
print(listoffields)

Answer 1

The JSON you posted contains misplaced quotes.
I think you are trying to extract the value of 'value' column within bills.
try this
print(listoffields[0][0]['value'])
which will print you 100.0 as str. use float() to use it in calculations.
---edit---
Say the JSON you having contains many JSON objects separated by commas as..
[{ first-entry },{ second-entry },{ third.. }, ....and so on]
..and you want to find the value of each bill in the each JSON obj..
may be the code below will work.-
bill_value_list = [] # to store 'value' of each bill
for bill_list in listoffields:
bill_value_list.append(float(bill_list[0]['value'])) # blill_list[0] will contain complete bill dictionary.
print(bill_value_list)
print(sum(bill_value_list)) # do something usefull
Paste it after the code you posted.(no changes to your code .. since it always works :-) )
