So, I would like to suggest that when running a json_normalize over a dataframe, I could set anoter column/series to be kept with the resulting dataframe. Alternative Solutions Concatenating commands is a solution, but not really "easy" (and I don´t know about performance impact using th...
然后用pd.json_normalize()规范化,这会创建一个新的df,需要重新加入到原始表中。
Sum across all NaNs in pandas returns zero How to select rows that do not start with some str in pandas? How to shift Pandas DataFrame with a multiindex? What is correct syntax to swap column values for selected rows in a pandas data frame using just one line?

在Pandas中,可以使用read_json()函数读取JSON数据,并将其转换为DataFrame对象进行进一步的处理和分析。对于深度嵌套的JSON数据,可以使用json_normalize()函数将其展平为扁平的结构,方便后续的数据处理。 对于带有选择键的深度嵌套JSON,可以使用json_normalize()函数的record_path参数指定选择键的路径,将选择键的值作为...

使用json_normalize创建嵌套JSON的DataFrame可以通过以下步骤实现: 导入必要的库: 代码语言:txt 复制 import pandas as pd from pandas.io.json import json_normalize 定义嵌套的JSON数据: 代码语言:txt 复制 data = { "name": "John", "age": 30, "address": { "street": "123 Main St", "city": ...

对于一个简单的类JSON字典,可以使用一个解析列表将值转换为值列表。下面是一个例子:...
