Python 标准化只生成一个大行

我有一个JSON文件，希望将其解析为一个数据帧。我希望有以下结构：

ID |事件|现场|

游戏1 |“额定子弹游戏”| |

游戏2 |“分级闪电战游戏”| |

但是，使用

df=pd.json\u normalize（所有行）

，df如下所示：

谢谢大家!

这个JSON的结构看起来可以使用默认的dataframe构造函数轻松地转换为dataframe：

df=pd.DataFrame（所有行）

您还可以使用函数更改数据方向：

df=pd.DataFrame（所有行）.T

如果此JSON中有大量嵌套对象，则可以使用JSON_规范化字典值中的dataframe，然后设置正确的索引：

df=pd.json\u规范化（列表（所有行.values（））
df.index=all_rows.keys（）
