While I am trying to retrieve values from JSON string, it gives me an error:
data = json.loads['{"lat":444, "lon":555}']
return data["lat"]
But, if I iterate over the data, it gives me the elements [lat and lon], but not the values:
data = json.loads['{"lat":444, "lon":555}']
ret = ''
for j in data:
ret = ret + ' ' + j
return ret
Which returns: lat lon
What do I need to do to get the values of lat and lon? [444 and
555]

If you want to iterate over both keys and values of the dictionary, do this:
for key, value in data.items[]:
print[key, value]

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']]

There's a Py library that has a module that facilitates access to Json-like dictionary key-values as attributes: //github.com/asuiu/pyxtension You can use it as:
j = Json['{"lat":444, "lon":555}']
j.lat + ' ' + j.lon

Using your code, this is how I would do it. I know an answer was chosen, just giving additional options.
data = json.loads['{"lat":444, "lon":555}']
ret = ''
for j in data:
ret = ret+" "+data[j]
return ret
When you use "for" in this manner you get the key of the object, not the value, so you can get the value by using the key as an index.
