我想創建一個2級index稱為combined這將是總和sales & last_sales所有的categories ，除了Facebook和total / Total 。 所以df看起來像這樣：
我嘗試用.loc來做，但沒有成功：
s = df_out.stack(0)
s['combined'] = 0
s.loc[(slice(None),[x for x in s.loc[(slice(None),:) if x != 'Facebook']].sum()
2 個解決方案
解決方案1
4 已采納 2021-07-22 10:33:43
解決方案
- 在
level=0刪除all，同樣在level=1drop其他不需要的級別值 - 計算
level=0上的sum以聚合幀 - 創建
Multindex以添加聚合幀中combined的附加級別 - 對索引進行追加和排序以保持順序
s = df.drop('all').drop(['Facebook', 'total', 'Total'], level=1).sum(level=0)
s.index = pd.MultiIndex.from_product([s.index, ['combined']])
df_out = df.append(s).sort_index()
結果
2020-06-29 00:00:00 2020-07-06 00:00:00 2021-06-28 00:00:00 2021-07-07 00:00:00

您可以在0級組，並concat每組的總和，如果name不是“所有”，同時加入索引。 然后將此輸出與原始數據和sort_index按level=0 ：
pd.concat([df,
pd.concat({(name, 'combined'): d.drop(['Facebook', 'total', 'Total'], level=1).sum()
for name,d in df.groupby(level=0) if name != 'all'}, axis=1).T
]).sort_index(level=0)
輸出：
2020-06-29 00:00:00 2020-07-06 00:00:00 2021-06-28 00:00:00 2021-07-07 00:00:00
