Answer 1

json_data is an instance of your file, not the content. so first apply read() on the instance for getting data. and second, write the full file name if you are reading a JSON file. your file should be testing.json. and third specify the mode of file opening mode. you can use this code

import json
with open('testing.json', 'r') as json_data:
    data = json.load(json_data.read())
    for element in data:
        del element['url']
