accessing elements in simplejson.load() output
i have a dictionary(?) of data returned from the simplejson.load() function. it looks like this...
{'status': 'OK', 'results': [{'geometry': {'location_type': 'APPROXIMATE', 'bounds': {'northeast': {'lat': 53.86121, 'lng': -2.045072}, 'southwest': {'lat': 53.80570600000001, 'lng': -2.162588}}, 'viewport': {'northeast': {'lat': 53.8697753, 'lng': -2.0725853}, 'southwest': {'lat': 53.81711019999999, 'lng': -2.2006447}}, 'location': {'lat': 53.84345099999999, 'lng': -2.136615}}, 'address_components': [{'long_name': 'Trawden', 'types': ['sublocality', 'political'], 'short_name': 'Trawden'}, {'long_name': 'Colne', 'types': ['locality', 'political'], 'short_name': 'Colne'}, {'long_name': 'Lancashire', 'types': ['administrative_area_level_2', 'political'], 'short_name': 'Lancs'}, {'long_name': 'United Kingdom', 'types': ['country', 'political'], 'short_name': 'GB'}], 'formatted_address': 'Trawden, Colne, Lancashire, UK', 'types': ['sublocality', 'political']}]}
How do I get at e.g. results->geometry->location->lat ?
Is this structure a regular python dictionary?
EDIT: please could someone also explain the simplejson.dumps() function. I don't find the docs very enlightening.
thanks
Edit by non-OP: here's the JSON, pretty-printed:
{
"status":"OK",
"results":[
{
"geometry":{
"location":{
"lat":53.843450999999988,
"lng":-2.1366149999999999
},
"location_type":"APPROXIMATE",
"viewport":{
"northeast":{
"lat":53.869775300000001,
"lng":-2.0725853000000001
},
"southwest":{
"lat":53.817110199999988,
"lng":-2.2006446999999998
}
},
"bounds":{

"lng":-2.0450719999999998

"southwest":{

}
Yes, it is. If you store it in a variable named d
, then you would use...
d['results'][0]['geometry']['location']
et cetera. Notice the [0]
there due to the fact that the dict with key 'geometry'
is inside a list.
simplejson.load()
maps JSON objects to Python dict
s and JSON lists to list
s. Very straightforward; don't overthink it.
simplejson.dumps()
simply does the opposite of simplejson.loads()
- it takes any standard Python object, and dumps it to a string which is a JSON representation of that object. For instance:
>>> q = {}
>>> q['foo'] = 'bar'
>>> q[1] = 'baz'
>>> simplejson.dumps(q)
'{"1": "baz", "foo": "bar"}'
