这是我的question的后续工作.而不是数据透视表,是否可以将表格展平为如下所示:
data = {'year': ['2016','2016','2015','2014','2013'],'country':['uk','usa','fr','uk'],'sales': [10,21,20,10,12],'rep': ['john','john','claire','kyle','kyle']
}
pd.DataFrame(data).pivot_table(index='country',columns='year',values=['rep','sales'])
rep sales
year 2013 2014 2015 2016 2013 2014 2015 2016
country
fr None kyle claire None None 10 20 None
uk kyle None None john 12 None None 10
usa None None None john None None None 21
扁平表:
rep_2013 rep_2014 rep_2015 rep_2016 sales_2013 sales_2014 sales_2015 sales_2016
country
fr None kyle claire None None 10 20 None
uk kyle None None john 12 None None 10
usa None None None john None None None 21
