[原] Python日期/时间操作方法使用
Python日期/时间操作方法使用0. 模块:
import os, sys
import time, datetime
1. 得到当前时间
(1) Based on time module:
import os, sys, time, datetime
startTime = time.localtime()
注意这里: startTime
(2) Based on datetime module:
import os, sys, time, datetime
nowTime = datetime.datetime.now()
type(nowTime)
2. 日期转字符串:
(1) str(xx)
(2) time提供的函数:
time.strftime(, time)
strStartTime = time.strftime('%Y-%m-%d %H:%M:%S', startTime)
'2009-06-03 13:44:51'
3. 字符串转日期:
(1) 字符串转time:
d = time.strptime(strStartTime, '%Y-%m-%d %H:%M:%S')
(2009, 6, 3, 13, 44, 51, 2, 154, -1)
type(d)
(2) 字符串转datetime
datetime的好处是可以实现方便的时间运算,比如 endTime - starTime,这在时间duration计算时非常方便.
# Convert string start time and end time to datetime.datetime
startTime = datetime.datetime(tmpStartTime, tmpStartTime, tmpStartTime, tmpStartTime,tmpStartTime, tmpStartTime );
基于上面的转换.
