python时间日期操作方法实例小结

本文实例讲述了python时间日期操作方法。分享给大家供大家参考，具体如下：

#coding=utf-8
import time
import datetime
if __name__ == "__main__":
 # 今天
 now = datetime.datetime.now()
 print now.strftime('%Y-%m-%d %H:%M:%S')
 print "%s-%s-%s %s:%s:%s" % (now.year, now.month, now.day, now.hour, now.minute, now.second)
 print time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
 # 前一天
 now = datetime.datetime.now()
 dt = now + datetime.timedelta(days=-1)
 print dt.strftime('%Y-%m-%d %H:%M:%S')
 print time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time() - 24 * 3600))
 # 后一天
 now = datetime.datetime.now()
 dt = now + datetime.timedelta(days=1)
 print dt.strftime('%Y-%m-%d %H:%M:%S')
 print time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time() + 24 * 3600))
 # 前一小时
 now = datetime.datetime.now()
 dt = now - datetime.timedelta(hours=1)
 print dt.strftime("%Y-%m-%d %H:%M:%S")
 print time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time() - 1 * 3600))
 # 时间戳 秒
 print int(time.time())
 # 时间戳 毫秒
 print int(round(time.time() * 1000))
 # 时间戳 to 日期
 print datetime.datetime.fromtimestamp(1507630854)
 print time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(1507630854))
 print time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
 # 日期 to 时间戳
 print time.mktime(time.strptime("2017-10-10", "%Y-%m-%d"))
 print time.mktime(time.strptime("2017-10-10 10:10:10", "%Y-%m-%d %H:%M:%S"))

运行结果：

2020-02-06 11:33:51
