python小白，字典列表嵌套，取值

best_ask=data["data"][0]["ask"][0][0]

{'table': 'spot/depth5', 'data': [{'asks': [['58546.7', '0.10271386', '16'], ['58553.4', '0.00144646', '2'], ['58553.5', '0.01', '1'], ['58553.7', '0.01069735', '1'], ['58556.1', '0.02', '1']], 'bids': [['58546.6', '4.1501877', '13'], ['58542.5', '0.0005', '1'], ['58542.3', '0.00125063', '2'], ['58542.2', '0.01118886', '1'], ['58541.9', '0.06602155', '1']], 'instrument_id': 'BTC-USDT', 'timestamp': '2021-04-09T12:28:02.680Z'}]}

请教，为什么取不到58546.7这个值呢？？

获取的就是58546.7啊, 你比较下你的代码和下面的代码. 你写的asks 少个 s

import pandas as pd
import numpy as np

dic = {'table': 'spot/depth5', 'data': [{'asks': [['58546.7', '0.10271386', '16'], 
                                                  ['58553.4', '0.00144646', '2'], 
                                                  ['58553.5', '0.01', '1'], 
                                                  ['58553.7', '0.01069735', '1'], 
                                                  ['58556.1', '0.02', '1']], 
                                         'bids': [['58546.6', '4.1501877', '13'],
                                                  ['58542.5', '0.0005', '1'], 
                                                  ['58542.3', '0.00125063', '2'], 
                                                  ['58542.2', '0.01118886', '1'], 
                                                  ['58541.9', '0.06602155', '1']], 
                                         'instrument_id': 'BTC-USDT', 
                                         'timestamp': '2021-04-09T12:28:02.680Z'}]}

df = dic['data'][0]['asks'][0][0]    

print(df)

print(df)
58546.7
