我知道函数json_normalize,但问题是当它到达“line_items”时,json_normalize无法处理并将所有内容放在DF中的同一列和同一行下。 据我所知,“Line_item”是另一个字典/对象,我的最终目标是将这个json平坦化,为“Line_items”之外的所有key:value创建一列,并为“Line_items”之内的每个项创建一个新行;“行项目”之外的信息会重复

我也尝试了下面的一个,定义了“路径”。但我遇到了这个错误:SyntaxError:positional参数跟在关键字参数后面

df2 = json_normalize(json_data['orders'], sep = "_",  
                     record_path = "line_items",
                     meta =

                     meta_prefix = "line_")

关于如何进行这种转变,有什么建议吗

可能重复发生
SyntaxError:positional参数跟随关键字参数
,因为您传递给
meta
参数的值未包含在括号中,因此它将第二个值(
fulfillment\u service
)视为新参数Hey@IanThompson,感谢您的参考,但我也研究了递归解决方案,但我并没有完全解决问题。我无法将文件完全展平,因为“line_items”对象中的“items”数量因事务而异。我需要弄清楚如何“平放”到第一个项目,然后根据一个事务的项目数创建行。这有意义吗?
