使用python处理每个用户一行中的数据
我从Google Analytics自定义报告生成的csv文件中收集用户数据，一些用户属性具有多个用户值。我的目标是获取用户数据，并将与一个用户相关的所有相关数据放在一行中 例如：使用python处理每个用户一行中的数据,python,csv,dataframe,export-to-csv,data-processing,Python,Csv,Dataframe,Export To Csv,Data Processing,我从Google Analytics自定义报告生成的csv文件中收集用户数据，一些用户属性具有多个用户值。我的目标是获取用户数据，并将与一个用户相关的所有相关数据放在一行中 例如： users = [ { id:1, name: 'user1'}, { id:2, name: 'user2'}, { id:3, name: 'user3'} ] products_purchased = [ {id:1 , product_purchased: 'sardines'},
