Python

Good afternoon
There is such a JSON and a script in Python. Which displays a list of companies on the screen.
How, for example, to display regions from Company1 or another by condition.

import os
import json
import requests

BASE_URL = 'localhost'

res = requests.get(BASE_URL)
res_content = json.loads(res.content)

for holding in res_content['data']:
    print(holding['id'], holding['attributes']['name'])

Answer 1

for data in res_content['data']:
  attributes = data['attributes']

  regions = attributes['regions']['data']
  name = attributes['name']
  print(name)
  for region in regions:
    print('--',region['attributes']['name'])
