在python中的特定时间运行函数 [英] Run function at a specific time in python

问题描述

import time
import webbrowser

print(time.ctime())

targetTime = time.ctime()


if(targetTime == "Tue May 01 11:05:17 2018"):    
    webbrowser.open("https://www.youtube.com/watch?v=dQw4w9WgXcQ")

这是我已经尝试过的，并且在时机成熟时它不会打开链接.我通读了时间图书馆，但找不到任何帮助我的东西.我的目标是让程序在我想要的时间打开一个链接.任何帮助表示赞赏.

This is what I tried already and it doesn't open the link when the time comes. I read through the time library but I couldn't find anything to help me. My target is for the program to open a link at a time that I want. Any help appreciated.

推荐答案

Python 内置了一个简单的调度库，名为 sched 支持这个.

Python comes built-in with a simple scheduling library called sched that supports this.

import sched, time

def action():
    webbrowser.open("https://www.youtube.com/watch?v=dQw4w9WgXcQ")

# Set up scheduler
s = sched.scheduler(time.localtime, time.sleep)
# Schedule when you want the action to occur
s.enterabs(time.strptime('Tue May 01 11:05:17 2018'), 0, action)
# Block until the action has been run
s.run()
