从JSON响应中提取

Question

I have a Python script that fetches a JSON response:

import requests
import json

bitcoin_api_url = 'https://example.com'
response = requests.get(bitcoin_api_url)
response_json = response.json()
print(response_json)

Result:

[{'id': 'bitcoin', 'name': 'Bitcoin', 'symbol': 'BTC', 'rank': '1', 'price_usd': '4068.19769898', 'price_btc': '1.0', '24h_volume_usd': '9967726932.86', 'market_cap_usd': '71664809254.0', 'available_supply': '17615862.0', 'total_supply': '17615862.0', 'max_supply': '21000000.0', 'percent_change_1h': '-0.42', 'percent_change_24h': '-0.01', 'percent_change_7d': '0.95', 'last_updated': '1553837126'}]

How can I extract values from this using Python? For example, I'd like to ask it for 'id' and get 'bitcoin' as a response.

Answer 1

simple code as per your requirement

   for i in d:
      print(i['id'])

Answer 2

It's returning a list containing a dictionary. Pull the dictionary out of the list, then you can grab individual values from the dictionary.

response_json = response.json()[0]
id = response_json['id']
