A value is trying to be set on a copy of a slice from a DataFrame 在为DataFrame对象新增一列数据时,报错“A value is trying to be set on a copy of a slice from a DataFrame”,原因是操作的数据不是原始数据,而是原始数据的视图。 解决方案:在新增列之前,显示复制原始数据。示例如下:......
The url column you got back has a list of numbers on the left. This is called the index, which uniquely identifies rows in the DataFrame. You will use the index to select individual rows, similar to how you selected rows from a list in an earlier lesson. A unique identifier is often ...

The following example takes the first DynamicFrame received, converts it to a DataFrame to apply the native filter method (keeping only records that have over 1000 votes), then converts it back to a DynamicFrame before returning it. def FilterHighVoteCounts (glueContext, dfc) -> DynamicFrame...
