Python List object to varaibles.

I have this List object and need to massage it a couple ways...

First I would like it to read without the {'attributes': at the front and the trailing }

Like this:

{'OBJECTID': 2, 'PERMITTEE': None, 'ROUTE': None, 'GLOBALID': '{8BF971DC-473B-4C88-8007-363EDAE7D091}', 'RELGLOBALID': '{F06AD758-9BBB-4096-942D-484F9F2B0435}', 'INSPECTOR_NAME': None, 'PERMIT_INTERNAL_ID': None}, 'geometry': {'x': -77.393420655, 'y': 37.615990732}

Second I would like to be able to set the OBJECTID, PERMITID, ROUTE etc to variables...

Thoughts?

{'attributes': {'OBJECTID': 2, 'PERMITTEE': None, 'ROUTE': None, 'GLOBALID': '{8BF971DC-473B-4C88-8007-363EDAE7D091}', 'RELGLOBALID': '{F06AD758-9BBB-4096-942D-484F9F2B0435}', 'INSPECTOR_NAME': None, 'PERMIT_INTERNAL_ID': None}, 'geometry': {'x': -77.393420655, 'y': 37.615990732}}

I guess my question is how to I access the Attribute Key and the Geometry Key and write their objects to variables.

This is what I am doing right now and ... querying a dataset and writing to json file and trying to read that and put into variables

unless there is a better way?

URL = targetURL + '/query' field = 'OBJECTID' whereclause = 'OBJECTID=2' PARAMS = {'token': portaltoken,'f': 'json', 'where': '{}'.format(whereclause), 'returnIdsOnly': False, 'returnCountOnly': False, 'returnGeometry': True, 'outFields': '*'} r = requests.post(url=URL, data=PARAMS) outjsonpath = outputVariable + "output.json" layer_data = r.json() layer_data_final = layer_data print('Writing JSON file...') with open(outjsonpath, 'w') as out_json_file: json.dump(layer_data_final, out_json_file) filetoImport = outjsonpath f = open(filetoImport) data = json.load(f) featureAddingAdd = data['features'] print(featureAddingAdd)

dictionary... not list, check python documentation for more information. Dictionaries have 'keys' and 'values' and they can be 'sliced'

d = {'attributes': {'OBJECTID': 2, 'PERMITTEE': None, 'ROUTE': None, 'GLOBALID': '{8BF971DC-473B-4C88-8007-363EDAE7D091}', 'RELGLOBALID': '{F06AD758-9BBB-4096-942D-484F9F2B0435}', 'INSPECTOR_NAME': None, 'PERMIT_INTERNAL_ID': None}, 'geometry': {'x': -77.393420655, 'y': 37.615990732}} d.keys() Out[2]: dict_keys(['attributes', 'geometry']) d['attributes'] # -- slice by the key {'OBJECTID': 2, 'PERMITTEE': None, 'ROUTE': None, 'GLOBALID': '{8BF971DC-473B-4C88-8007-363EDAE7D091}', 'RELGLOBALID': '{F06AD758-9BBB-4096-942D-484F9F2B0435}', 'INSPECTOR_NAME': None, 'PERMIT_INTERNAL_ID': None} d['attributes']['GLOBALID'] '{8BF971DC-473B-4C88-8007-363EDAE7D091}'
