用python循环遍历json响应对象

Question

我正在尝试循环包含数据的json响应对象。我想循环思考json对象并提取for键event-id，market-id和event-participant-name。 json响应如下

                  },

当我循环思考这个JSON对象时，我得到一个关键错误。如何循环此对象并返回每个属性的每个值？

码

def match_book_get(self):

   tennis_events = self.api.market_data.get_events(sport_ids= 
   [9],states=MarketStates.All, per_page=10000, offset=0,
                                include_event_participants=Boolean.T, 
   price_depth=3, side=Side.All)

   data = []

   for data in tennis_events:
       event_id = data['event_id']
       market_id = data['market-id']
       evparid = data['event-participant-id']

Answer 1

从JSON响应中可以看出，您要查找的键位于markets和runners键下的列表中。您应该使用以下内容：

for data in tennis_events:
    for market in data['markets']:
       event_id = market['event-id']
       for runner in market['runners']:
           market_id = runner['market-id']
           evparid = runner['event-participant-id']
