Question

在这里我需要根据其他列创建新列

样本数据：

colum1       column2

M           online

L           offline

C           online

L           online

H           online

M           online

L           offline

C           online

L           offline

在这里我需要创建新列

column1 ='M'＆colum2 ='online'-> 3天

Column1 ='M'＆colum2 ='offline'-> 5天

像这样，我需要创建一个新列

尝试下面的代码，但我错过了逻辑

sales['Shipment Tat'] = np.where ((sales['Order Priority'] == 'M') & (sales['Sales Channel'] == 'Online') ,  'with in 9 days' )

预期产量

column1    column2       column3

M           online     3 days

M           offline    5 days

L           offline    5 days

C           online     7 days

L           online     7 days

H           online     9 days

H           offline    11 days
