在python中使用高精度时间戳 [英] working with high precision timestamps in python

问题描述

嘿，我正在使用带日期时间的python工作，我想知道解析此时间戳的最佳方法是什么.

Hey I am working in python with datetime and I am wondering what the best way to parse this timestamp is.

时间戳是ISO标准，下面是示例"2010-06-19T08:17:14.078685237Z"

The timestamps are ISO standard, here is an example "2010-06-19T08:17:14.078685237Z"

到目前为止，我已经使用过

Now so far I have used

time = datetime.datetime.strptime(timestamp.split(".")[0], "%Y-%m-%dT%H:%M:%S")
precisetime = time + datetime.timedelta(0,float("." + timestamp[:-1].split(".")[0]))

这种类型的作品，但是我觉得应该有一种更简化的方式(我对python还是很陌生，我敢肯定我会像个屁股那样做).另外，我的时间戳中有纳秒，但日期时间对象中只有微秒，是否有更好的模块可以使用?我需要能够对时间进行操作，例如减去时间并将其放入调度程序中.

This kind of works, but I feel like there should be a more streamlined way (I am very new to python, and I am sure I am doing this like an ass). Also, I have nanoseconds in my timestamp, but only microseconds in my datetime object, is there a better module to work with? I need to be able to do operations on the time such as subtracting times and putting them in the scheduler.

有更好的方法吗?

推荐答案

您的方法天生就没有驴子般的味道，但是您可能想尝试 dateutil

There's nothing inherently ass-like with your approach, but you may like to try pyiso8601 or dateutil
