Get seconds since midnight in python

pythondatedatetime

提问by linqu

I want to get the seconds that expired since last midnight. What's the most elegant way in python?

我想获取自上次午夜以来过期的秒数。python中最优雅的方式是什么?

采纳答案by eumiro

It is better to make a single call to a function that returns the current date/time:

最好对返回当前日期/时间的函数进行一次调用:

from datetime import datetime

now = datetime.now()
seconds_since_midnight = (now - now.replace(hour=0, minute=0, second=0, microsecond=0)).total_seconds()

Or does

或者做

datetime.now() - datetime.now()

return zero timedelta for anyone here?

为这里的任何人返回零时间增量?

回答by linqu

I would do it that way

我会那样做

import datetime
import time

today = datetime.date.today()
seconds_since_midnight = time.time() - time.mktime(today.timetuple())

回答by Lennart Regebro

import datetime
now = datetime.datetime.now()
midnight = now.replace(hour=0, minute=0, second=0, microsecond=0)
seconds = (now - midnight).seconds

or

或者

import datetime
now = datetime.datetime.now()
midnight = datetime.datetime.combine(now.date(), datetime.time())
seconds = (now - midnight).seconds

Which to choose is a matter of taste.

选择哪个是品味问题。
