Why can't Python parse this JSON data?

Question

This my my JSON: { "maps": [ { "id": "AT", "iscategorical": "0" }, { "id": "AT", "iscategorical": "0" } ], "masks": [ "id": "Jaipur" ], "om_points": "Outcome", "parameters": [ "id": "Jaipur" ] } To print the JSON data I wrote this: import json from pprint import pprint with open('data.json') as f: data = json.load(f) pprint(data) but I faced an exception raised by the program: Traceback (most recent call last): File "", line 5, in data = json.load(f) File "/usr/lib/python3.5/json/__init__.py", line 319, in loads return _default_decoder.decode(s) File "/usr/lib/python3.5/json/decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib/python3.5/json/decoder.py", line 355, in raw_decode obj, end = self.scan_once(s, idx) json.decoder.JSONDecodeError: Expecting ',' delimiter: line 13 column 13 (char 213) I want to parse the JSON and extract the values, How can I do it?

The data you are using is not valid JSON format, You should use { } instead [ ] : [ ] is for JSON arrays, and it's used for list in Python. whereas { } is for for JSON objects, and it's used for dict in Python. This is what you can use: { "maps": [ { "id": "AT", "iscategorical": "0" }, { "id": "AT", "iscategorical": "0" } ], "masks": { "id": "Jaipur" }, "om_points": "output", "parameters": { "id": "Jaipur" } } so you can use this code: import json from pprint import pprint with open('data.json') as d: data = json.load(d) pprint(data) Using this data you can also find values like: data["maps"][0]["id"] data["masks"]["id"] data["om_points"] Try these codes and if you have any doubts you can ask them in comments.
