json = json.dumps(response.json(), sort_keys=True, indent=4)

print(json)

Answer 1

You need to sort the response before dumps() -ing it

import requests
import json

response = requests.get('https://dataapi.moc.go.th/export-commodity-countries?year=2017&month=12&com_code=101010200&limit=3', verify=False)
# get the data
response_data = response.json()
# sort it based on quantity
response_data.sort(key=lambda entry: entry['quantity'])
# now print
json_str = json.dumps(response_data, sort_keys=True, indent=4)

print(json_str)
