1. 計(jì)算給出兩個(gè)時(shí)間之間的時(shí)間差
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. 獲取n天前的時(shí)間
cur_time = dt.now()# previous n dayspre_time = dt.timedelta(days=n)
3. 將給定的時(shí)間精確到天或者其他單位
cur_time = dt.now()# get day of current timecur_day = cur_time.replace(hour=0, minute=0, second=0, mircrosecond=0)
4. 獲取一連串的時(shí)間序列（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. 將時(shí)間字符串轉(zhuǎn)化為datetime類型
date_formate = "%Y-%m-%d" # year-month-daytime = dt.strptime('2016-06-22', date_format)6. 將時(shí)間類型轉(zhuǎn)化為字符串類型
time_str = dt.strftime("%Y-%m-%d", dt.now()) # return like "2016-06-22"以上就是小編為大家?guī)淼臏\談Python中用datetime包進(jìn)行對(duì)時(shí)間的一些操作全部?jī)?nèi)容了，希望大家多多支持武林網(wǎng)~
