Getting values from JSON using Python

What error is it giving you?

If you do exactly this:

data = json.loads('{"lat":444, "lon":555}')

Then:

data['lat']

SHOULD NOT give you any error at all.

Using Python to extract a value from the provided Json

Working sample:

import json
import sys

# load the data into an element
data = {"test1": "1", "test2": "2", "test3": "3"}

# dumps the json object into an element
json_str = json.dumps(data)

# load the json to a string
resp = json.loads(json_str)

# print the resp
print(resp)

# extract an element in the response
print(resp['test1'])

If you want to iterate over both keys and values of the dictionary, do this:

for key, value in data.items():
    print(key, value)
