Question

我有一个api的json输出，其格式如下，我想将其带入熊猫数据框。

pd.read_json可以使用哪种语法，以便可以在列中使用正确的格式？

我尝试使用orient = index和orient = columns将其带入数据帧，但它给出了错误

尝试使用json_normalize：

d是您上面粘贴的字典：

df = pd.json_normalize(d, record_path=['tickers'], meta=['name'])
print(df)

   base target          last        volume trust_score  ...  converted_last.usd converted_volume.btc converted_volume.eth converted_volume.usd     name
0  BUSD   USDT      1.000100  7.528649e+07       green  ...                1.00             7087.000               220031             75445315  Binance
1   BTC   USDT  10623.850000  3.912786e+04       green  ...            10626.77            39060.000              1212659            415802842  Binance
