我正在尝试创建一个index名为2 的级别combined，它将是除and /之外sales & last_sales的所有内容的总和。这样看起来像这样：categoriesFacebooktotalTotaldf
我尝试这样做，.loc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()
解决方案
- 放入，类似地，
all将其他不需要的级别值放入level=0droplevel=1 - 计算聚合帧的
sumonlevel=0 - 创建以在聚合框架中
Multindex添加附加级别combined - 对索引进行追加和排序以维持顺序
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()
结果
2020-06-29 00:00:00 2020-07-06 00:00:00 2021-06-28 00:00:00 2021-07-07 00:00:00
last_sales sales difference last_sales sales difference last_sales sales difference last_sales sales difference
