使用 python 从 JSON 获取特定数据

Question

我想从 JSON 中获取特定数据。 现在我可以获取所有数据并将其转换为 JSON 格式。 但我只想获取所有集合的“home_team”和“away_team”。

我获取所有数据的代码是：`

import json
import requests

reap = requests.get('https://app.sportdataapi.com/api/v1/soccer/matches?apikey=64572f90-88d6-11eb-8a43-7106c933e99d&season_id=496&date_from=2020-09-19&fbclid=IwAR2zkLfVHG1xyxCrKQdcvCqhYhyjp5vA2TtbAsXZ3R3pVFJKV3jnhgFdjG4')
data = reap.json()
print(data)

而我的 JSON 数据是：

{'query': {'apikey': '64572f90-88d6-11eb-8a43-7106c933e99d', 'season_id': '496', 'date_from': '2020-09-19', 'fbclid': 'IwAR2zkLfVHG1xyxCrKQdcvCqhYhyjp5vA2TtbAsXZ3R3pVFJKV3jnhgFdjG4'}, 'data': [{'match_id': 139415, 'status_code': 3, 'status': 'finished', 'match_start': '2020-09-19 13:30:00', 'match_start_iso': '2020-09-19T13:30:00+00:00', 'minute': None, 'league_id': 314, 'season_id': 496, 'stage': {'stage_id': 1, 'name': 'Regular Season'}, 'group': {'group_id': 222, 'group_name': 'Bundesliga'}, 'round': {'round_id': 18564, 'name': '1', 'is_current': None}, 'referee_id': 433, 'home_team': {'team_id': 3993, 'name': '1.

现在，如果我这样做：

print(data['data'])

它还向我显示了除查询和查询的内部数据之外的所有数据。

响应中的data键 JSON 是 dict 列表，您可以使用 for 循环遍历列表并访问away_team和home_team字典。

for d in data['data']:
    print(d['home_team'])
    
for d in data['data']:
    print(d['away_team'])
