python datetime unix时间戳以及字符串时间戳转换
将python的datetime转换为unix时间戳
import time import datetime dtime = datetime.datetime.now() ans_time = time.mktime(dtime.timetuple())
将unix时间戳转换为python的datetime
import datetime unix_ts = 1439111214.0 time = datetime.datetime.fromtimestamp(unix_ts)
Python time & datetime & string 相互转换

输出结果:
1.把datetime转成字符串: 2017-11-23 17:05:18 2.把字符串转成datetime: 2017-11-23 16:10:10 3.把字符串转成时间戳形式: 1511424610.0 4.把时间戳转成字符串形式: 2017-11-23 17:05:18 5.把datetime类型转外时间戳形式: 1511427918.0
