如果数据如下:
Store,Dept,Date,Weekly_Sales,IsHoliday
1,1,2010-02-05,24924.5,FALSE
1,1,2010-02-12,46039.49,TRUE
1,1,2010-02-19,41595.55,FALSE
1,1,2010-02-26,19403.54,FALSE
1,1,2010-03-05,21827.9,FALSE
1,1,2010-03-12,21043.39,FALSE
1,1,2010-03-19,22136.64,FALSE
1,1,2010-03-26,26229.21,FALSE
1,1,2010-04-02,57258.43,FALSE
我想复制IsHoliday等于TRUE的行,我可以这样做:
is_hol = df['IsHoliday'] == True
df_try = df[is_hol]
df=df.append(df_try*10)
但有没有更好的方法来做到这一点因为我需要将假日行复制5次,如果使用上述方法我必须追加5次.
