python中使用pandas提取日期信息

提取日期操作参照→链接：https://blog.csdn.net/meiqi0538/article/details/82558000

import numpy as np
import pandas as pd
from pandas import Series, DataFrame
from datetime import datetime
 
data = {'stamp': ['2016-12-01 00:00:00', '2016-12-01 01:05:10' ,'2016-12-01 02:10:20', '2016-12-01 03:15:30',
                 '2016-12-01 04:20:40','2016-12-01 05:25:50','2016-12-01 06:30:00','2016-12-01 07:35:10',
                  '2016-12-01 08:40:20','2016-12-01 09:45:30','2016-12-01 10:50:40','2016-12-01 11:55:50'],
}
df = pd.DataFrame(data)
df

结果如下：

提取数据中日期：

from pandas import to_datetime
df_dt=to_datetime(df.stamp)
s_y=df_dt.dt.year
s_M
