How can I use Python to increment 'tokenId' values in a .json file?
To increase the values of the "tokenId" field in your JSON file by 1, you can modify your code as follows:
import json

with open('traits.json') as f:
    data = json.load(f)

for item in data:
    item['tokenId'] += 1

with open('new_data.json', 'w') as f:
    json.dump(data, f)

In your original code, you were trying to access data['tokenId'] as if it was a list, but it is actually a dictionary. Instead, you need to iterate over the list data and update the "tokenId" field of each item. By using item['tokenId'] += 1, you increment the value of "tokenId" by 1.
Finally, the modified data is saved to a new JSON file named "new_data.json" using json.dump(data, f).
After running this code, the "new_data.json" file will contain the updated "tokenId" values with an increment of 1.

I have a .json file but I got the tokenId numbering wrong. I need to increase all values of "tokenId" by 1 number
[
    {
        "Background": "Red",
        "Body": "Tunn",
        "Hat": "Bambu",
        "Outfit": "Pirate",
        "Expression": "Sad",
        "Accessory": "Rifle",
        "tokenId": 0
    },
    {
        "Background": "Lilac",
        "Body": "Tunn",
        "Hat": "Bicorn",
        "Outfit": "Pirate",
        "Expression": "Angry",
        "Accessory": "Balloons",
        "tokenId": 1
    },

          ...
    
    {
        "Background": "Green",
        "Body": "Tunn",
        "Hat": "Bicorn",
        "Outfit": "Pirate",
        "Expression": "Sad",
        "Accessory": "Balloons",
        "tokenId": 3000
    },


is it possible to do this with python? i created this .json file with python.
I tried this code, but I get an error
import json

with open('traits.json') as f:
    data = json.load(f)

for item in data['tokenId']:
    item['tokenId'] = item['tokenId'].replace([int('+1')])

with open('new_data.json', 'w') as f:
    json.dump(data, f)

TypeError: list indices must be integers or slices, not str

Thank you!
