当前输出为
|by app
|[{'app': 5, 'cat': 3,...
预期输出是
|app |cat |rx_byte|rx_packets|....
|5 |3 |60837 |203 |....
我试图将列分成单独的列，而不是将它们集中到 1 列中
【问题讨论】：
-
扁平化首先将字典放入列表中......？
-
您的 json 对象在顶层具有三个键，csv 文件需要二维数据，但您有多个维度。首先你有 3 个根级键，然后每个键都有它的对象列表。那么，您的 csv 与这些数据究竟应该是什么样子？
-
我只是想将所有内容分成一列，每列都有类似的标题，如数据库表
-
也许可以先查看以下链接以展平您的 json，然后使用 pandas 的 datafram to_csv 方法：
