Python 提取月份和月份中的周

我目前正在使用DateTime对象处理pandas数据帧。有没有办法从pandas datetime对象中提取month weekofthemonth

data = pd.DataFrame(pd.date_range(' 1/ 1/ 2020', periods = 7, freq ='D'))

0  2000-01-01
1  2000-01-02
2  2000-01-03
3  2000-01-04
4  2000-01-05
5  2000-01-06
6  2000-01-07

Expected:

0  2000-01-01       01-01
1  2000-01-02       01-01
2  2000-01-03       01-01
3  2000-01-04       01-01
4  2000-01-05       01-01 
5  2000-01-06       01-01
6  2000-01-07       01-01
7  2000-01-08       01-02 
8  2000-01-09       01-02
9  2000-01-10       01-02

基于

应该给

0    01-01
1    01-01
2    01-01
3    01-01
4    01-01
5    01-01
6    01-01
7    01-02
8    01-02
9    01-02

名称：0，数据类型：对象参见

这将为您提供：

           0   WoM
0 2020-01-01  1-01
1 2020-01-02  1-01
2 2020-01-03  1-01
3 2020-01-04  1-01

7 2020-01-08  1-02
8 2020-01-09  1-02
9 2020-01-10  1-02

import pandas as pd

data = pd.DataFrame(pd.date_range(' 1/ 1/ 2020', periods = 10, freq ='D'))
data['WoM'] = data[0].apply(lambda d : str(d.month) + '-0'+str(d.day//8+1))
print(data)

           0   WoM
