我必须创建一个名为Public_Holiday_Week的条件列,如果该特定周有公共假日,则该列应返回1
我希望看到这样的输出
Date WeekNum Public_Holiday Public_Holiday_Week
1/1/2015 1 1 1
2/1/2015 1 0 1
3/1/2015 1 0 1
4/1/2015 1 0 1
5/1/2015 1 0 1
6/1/2015 1 0 1
7/1/2015 1 0 1
8/1/2015 2 0 0
9/1/2015 2 0 0
10/1/2015 2 0 0
11/1/2015 2 0 0
12/1/2015 2 0 0
13/1/2015 2 0 0
我尝试使用np.where
df['Public_Holiday_Week'] = np.where(df['Public_Holiday']==1,1,0)
但是,如果不是公众假期,它适用于本周其他日子的0.
我必须在这里申请滚动吗？感谢您的帮助
解决方法:
使用resample并完全跳过WeekNum列的使用.
df.assign(
Public_Holiday_Week=
df.resample('W-Wed', on='Date').Public_Holiday.transform('max')
)
Date WeekNum Public_Holiday Public_Holiday_Week
