非轮询/非阻塞定时器? [英] Non-polling/Non-blocking Timer?

问题描述

目前我发现的最佳解决方案是使用 sleep() 函数.当计时器到期事件发生时，我想运行我自己的回调函数.有没有任何事件驱动的方法来解决这个问题?

The best solution I've found so far is to just use the sleep() function. I'd like to run my own callback function when the event of a timer expiration happens. Is there any event-driven way to go about it?

from time import sleep

# Sleep for a minute
time.sleep(60)

推荐答案

有一个内置的简单解决方案，使用 线程 模块:

There's a built-in simple solution, using the threading module:

import threading

timer = threading.Timer(60.0, callback)
timer.start()  # after 60 seconds, 'callback' will be called

## (in the meanwhile you can do other stuff...)

您还可以将 args 和 kwargs 传递给您的回调.请参阅此处.

You can also pass args and kwargs to your callback. See here.
