我有数据帧just_dates
:
0 2003-01-02
1 2015-10-31
2 2015-11-01
16 2015-11-02
33 2015-11-03
44 2015-11-04
以及一个数据帧
df['weeks'] = pd.PeriodIndex(df.just_dates, freq='W')
weeks
看起来像:0 2002-12-30/2003-01-05
1 2015-10-26/2015-11-01
2 2015-10-26/2015-11-01
16 2015-11-02/2015-11-08
33 2015-11-02/2015-11-08
44 2015-11-02/2015-11-08
现在我想要一个数据框架,包含从第一周到最后一周之间的所有周,所以
weeks
应该看起来像:0 2002-12-30/2003-01-05
1 2003-01-06/2003-01-12
2 2003-01-13/2003-01-19
...
2015-10-26/2015-11-01
2015-10-26/2015-11-01
2015-11-02/2015-11-08
2015-11-02/2015-11-08
2015-11-02/2015-11-08
有什么简单的方法可以做到这一点吗?
最佳答案
pd.DataFrame(pd.period_range(start=df.weeks.min(),
end=df.weeks.max(),
freq='W'))
