Not sure how to do it?
您还可以通过以下方式获得确切的格式：
pd.DataFrame(my_json).T.rename_axis(columns='Date')
Date open high low close volume
2017-01-03 214.86 220.33 210.96 216.99 5923254.0
2017-12-29 316.18 316.41 310.00 311.35 3777155.0
您还可以直接从数据中读取以获取缺少日期的格式：
pd.DataFrame.from_dict(my_json, orient='index').rename_axis(columns='Date')
Date open high low close volume
2017-01-03 214.86 220.33 210.96 216.99 5923254
2017-12-29 316.18 316.41 310.00 311.35 3777155
