1. 计算给出两个时间之间的时间差
1
2
3
4
5

import datetime as dt # current time cur_time = dt.datetime.today() # one day pre_time = dt.date( 2016 , 5 , 20 ) # eg: 2016.5.20 delta = cur_time - pre_time # if you want to get discrepancy in days print delta.days # if you want to get discrepancy in hours print delta.hours # and so on |
2. 获取n天前的时间
1
2
3
|
cur_time = dt.now() # previous n days pre_time = dt.timedelta(days = n) |
3. 将给定的时间精确到天或者其他单位
1
2
3
|
cur_time = dt.now() # get day of current time cur_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)
1
2
|
cur_time = dt.datetime.today() datelist = [cur_time - dt.timedelta(days = x) for x in range ( 0 , 100 )] |
或者
1
2
|
import pandas as pd datelist = pd.date_range(pd.datetime.today(), periods = 100 ).tolist() |
5. 将时间字符串转化为datetime类型
1
2
|
date_formate = "%Y-%m-%d" # year-month-day time = dt.strptime( '2016-06-22' , date_format) |
6. 将时间类型转化为字符串类型
1
|
time_str = dt.strftime( "%Y-%m-%d" , dt.now()) # return like "2016-06-22" |
