我正在尝试创建一个名为 combined 的级别 2 index，它将是除 categories 之外的所有 sales & last_sales 的总和，Facebook 和 total / Total 除外。
所以df 看起来像这样：
我尝试使用.loc 进行操作，但没有成功：
s = df_out.stack(0)
s['combined'] = 0
s.loc[(slice(None),[x for x in s.loc[(slice(None),:) if x != 'Facebook']].sum()
【问题讨论】：
-
您要排除
level=1中的Total和total类别吗？ -
是的，会更新我的问题表述。
-
this 能回答你的问题吗？
