How to change the output of json to match converted formatting in python-CodePudding

The source code for the json is from a json file that contains output as shown below

 [{
    "text": "text to be shown",
    "label": [
        {
            "text": "text to be shown",
            "purpose": "scoping",
            "starting": 13,
            "ending": 20
        }
    ]
}]

I want to remove or ignore the name of the keys within the label attribute, but retain the value within it. So that the final output will read as below

[{
    "text": "text to be shown",
    "label": [["text to be shown","scoping",13,20]]
}]

CodePudding user response：

Assuming that the json file is saved as 'data.json' and is within the same folder as your script, do:

#run this in python3
import json


with open('data.json', 'r') as f:
    data = json.loads(f.read())

data[0]['label'][0] = list(data[0]['label'][0].values())
print(data)

You should see:

[{'text': 'text to be shown', 'label': [['text to be shown', 'scoping', 13, 20]]}]

Why this works: Remember that lists are mutable. Thus you can reassign the list contents in its place and the modifications will be reflected within the same object.

Cheers!
