将任务延迟到某一时刻 [英] delay a task until certain time

问题描述

我想在python脚本中做的是睡几秒钟，直到达到所需的时间。 IE：如果runAt设置是15:20，当前时间是10:20，我该如何计算出几秒钟睡眠？我不知道如何将15:20转换成一个时间和当前日期，然后扣除实际的时间来获得秒数。

What I want to do in a python script is sleep a number of seconds until the required time is reached. IE: if runAt setting is 15:20 and current time is 10:20, how can I work out how many seconds to sleep? I'm not sure how to convert 15:20 to a time and current date then deduct the actual time to get the seconds.

推荐答案

p>想想您也可以使用以下代码：

Think you can also use the following code:

from datetime import datetime, time
from time import sleep

def act(x):
    return x+10

def wait_start(runTime, action):
    startTime = time(*(map(int, runTime.split(':'))))
    while startTime > datetime.today().time(): # you can add here any additional variable to break loop if necessary
        sleep(1)# you can change 1 sec interval to any other
return action

wait_start('15:20', lambda: act(100))
