import datetime as dt# current timecur_time = dt.datetime.today()# one daypre_time = dt.date(2016, 5, 20) # eg: 2016.5.20delta = cur_time - pre_time# if you want to get discrepancy in daysprint delta.days# if you want to get discrepancy in hoursprint delta.hours# and so on
2. 获取n天前的时间
cur_time = dt.now()# previous n dayspre_time = dt.timedelta(days=n)
3. 将给定的时间精确到天或者其他单位
cur_time = dt.now()# get day of current timecur_day = cur_time.replace(hour=0, minute=0, second=0, mircrosecond=0)
4. 获取一连串的时间序列（返回list）
cur_time = dt.datetime.today()datelist = [cur_time - dt.timedelta(days=x) for x in range(0, 100)]
或者
import pandas as pddatelist = pd.date_range(pd.datetime.today(), periods=100).tolist()
5. 将时间字符串转化为datetime类型
date_formate = %y-%m-%d # year-month-daytime = dt.strptime('2016-06-22', date_format)
6. 将时间类型转化为字符串类型
time_str = dt.strftime(%y-%m-%d, dt.now()) # return like 2016-06-22
