python能把正常时间转化成毫秒级别的时间戳吗 有字符串“2018-03-28 16:55:57.956”，...
Python\u80fd\u4e0d\u80fd\u4ea7\u751f\u5fae\u79d2\u7ea7\u522b\u7684\u65f6\u95f4\u6233time.time()\u5c31\u53ef\u4ee5, \u4e581000\u5c31\u884c\u4e86
>>> import time>>> time.time()1509890332.4617682
datetime.datetime.strptime("2018-03-28 16:55:57.956", "%Y-%m-%d %H:%M:%S.%f")
可以，需要乘以1000，比如
import time
print time.time()*1000#这个就是毫秒级别的时间戳，不乘以1000就是秒级时间戳
又如正常时间转换为时间戳，下面的例子需要你安装时间扩展arrow,安装方法很简单
pip install arrow，这都是废话了，下面上例子
import arrow
datetime="2016-12-22 22:30:50+08:00"
print arrow.get(datetime).timestamp#这个是秒级别的时间戳，乘以1000就是毫秒级别的时间戳了
