JSON to multiple dictionaries

Question

I have a JSON data as follows

 '{"item_id": "0", "start": "2015-06-01 00:00:00", "target": [1.5, 1.545, 6.79, ]}\n{"item_id": "1", "start": "2015-06-01 00:00:00", "target": [254.7725, 136.0975, 181.28, 167.09, 206.25, 147.2075, ]}\n{"item_id": "3", "start": "2015-06-01 00:00:00", "target": [361.13, 254.925, 160.05, 0.0, 255.915, 95.37, 133.32, 297.33, 99.275, 357.5, 43.12, 118.58, 99.0, 348.48, 79.2, 141.625]}'

How do I create a list of dictionaries from this JSON?

Answer 1

It looks like there's some trailing commas in some of the lists, but removing those, you can use .split() to split the string into individual JSON blobs, and then apply json.loads() to each of those blobs as you would with any other JSON string:

[json.loads(item) for item in data.split("\n")]

This outputs:

[
 {'item_id': '0', 'start': '2015-06-01 00:00:00', 'target': [1.5, 1.545, 6.79]},
 {'item_id': '1', 'start': '2015-06-01 00:00:00', 'target': [254.7725, 136.0975, 181.28, 167.09, 206.25, 147.2075]},
 {'item_id': '3', 'start': '2015-06-01 00:00:00', 'target': [361.13, 254.925, 160.05, 0.0, 255.915, 95.37, 133.32, 297.33, 99.275, 357.5, 43.12, 118.58, 99.0, 348.48, 79.2, 141.625]}
