Python 在 json 文本文件中搜索和替换

Question

how do i replace number inside "id": "1", and increment the number by +1 also remove the quotes around the number "id": 1 should look like this.

Here is an example of the json file, but it's huge. So doing this automatic by python would save alot of time

[
    {
      "id": "1",
      "text": "How old can a sea turtle get?",
    },
    {
      "id": "2",
      "text": "How many fishes are in the lake?",
    }
]

This is how far i got:

import re

with open("new 2.txt") as file:
    for line in file.readlines():
        x = re.findall('"id": "[a-zA-z]{0,1}[0-9]*"', line)

Use the json module, not regex.

import json

with open('new.txt') as f:
    records = json.load(f)
for item in records:
    item['id'] = int(item['id']) + 1
with open('updated.txt') as f:
    json.dump(records, f, indent=4)

Et voila:

[
    {
        "id": 2,
        "text": "How old can a sea turtle get?"
    },
    {
        "id": 3,
        "text": "How many fishes are in the lake?"
    }
]
