E:\PycharmProjects\DatawhaleChina\joyful-pandas\data\ 一、时序中的基本对象 总结出官方文档中的这个表格: datetime64[ns] 本质上可以理解为一个大整数,对于一个该类型的序列,可以使用 max, min, mean ,来取得最大时间戳、最小时间戳和“平均”时间戳。
一, datetime.datetime() import datetime dt = datetime.datetime(year=2019,month=11,day=4,hour=10,minute=30) dt datetime.datetime(2019, 11, 4, 10, 30) print(dt) 2019-11-04 10:30:00 二, pd.Timestamp() import pandas as pd
