How to delete an element in a json file python

Question

I am trying to delete an element in a json file,

here is my json file:

before:

{
    "names": [
        {
            "PrevStreak": false,
            "Streak": 0,
            "name": "Brody B#3719",
            "points": 0
        },
        {
            "PrevStreak": false,
            "Streak": 0,
            "name": "XY_MAGIC#1111",
            "points": 0
        }
    ]
}

after running script:

{
    "names": [
        {
            "PrevStreak": false,
            "Streak": 0,
            "name": "Brody B#3719",
            "points": 0
        }
    ]
}

how would I do this in python? the file is stored locally and I am deciding which element to delete by the name in each element

Thanks

Answer 1

You will have to read the file, convert it to python native data type (e.g. dictionary), then delete the element and save the file. In your case something like this could work:

import json

filepath = 'data.json'
with open(filepath, 'r') as fp:
    data = json.load(fp)
del data['names'][1]

with open(filepath, 'w') as fp:
    json.dump(data, fp)

Answer 2

I would load the file, remove the item, and then save it again. Example:

import json
with open("filename.json") as f:
    data = json.load(f)
f.pop(data["names"][1]) # or iterate through entries to find matching name
with open("filename.json", "w") as f:
    json.dump(data, f)
