I’m making a JSON change detector that lets the user either accept or decline the changes.

import json
import time

def detect_new_keys(file_path):
    existing_data = {}
    with open(file_path, 'r') as file:
        existing_data = json.load(file)

    keys = []
    for key in existing_data.keys():
        keys.append(key)

    while True:
        new_data = {}
        with open(file_path, 'r') as file:
            new_data = json.load(file)

        new_keys = []
        for key in new_data.keys():
            new_keys.append(key)

        new_keys_only = [key for key in new_keys if key not in keys]

        print("New keys added:", new_keys_only)

        time.sleep(5)

detect_new_keys('reports.json')

The provided code doesn’t find the changes. Please add if user input is n it deletes the key.

I expect it to say “New keys added: newKey”
