How to format json so I can parse floats and strings

I am getting the error when I try to run the following code. I know it has something to do with the formating of the json file but I am not sure how to proceed/change in order to be able to get floats from the json file

print(location['latitude'])
TypeError: string indices must be integers

my code

import requests
import bs4 as bs
import urllib.parse
import json
from datetime import datetime, timedelta
import time
import re

req = requests.get(url).text

search = re.search(r'window.__INITIAL_STATE__ = ({.*});', req).group(1)

data = json.loads(search)


# print(data.keys())

# print(json_object)

for location in data['listingReducer']['geoCode']:
    print(location['latitude'])

Answer

data['listingReducer']['geoCode'] is a dict so doing for location in data['listingReducer']['geoCode']gives you the keys

.

.
# print(data.keys())

# print(json_object)

# for location in data['listingReducer']['geoCode']:
#     print(location['latitude'])
print(data['listingReducer']['geoCode']['latitude'])
