Python 时间延迟 [英] Python Time Delays

问题描述

我想知道如何在一段时间后调用函数.我试过 time.sleep() 但这会停止整个脚本.我希望脚本继续运行，但在 ???secs 调用一个函数并同时运行另一个脚本之后

I want to know how to call a function after a certain time. I have tried time.sleep() but this halts the whole script. I want the script to carry on, but after ???secs call a function and run the other script at the same time

推荐答案

看看 threading.Timer.它在新线程中运行您的函数.

Have a look at threading.Timer. It runs your function in a new thread.

from threading import Timer

def hello():
    print "hello, world"

t = Timer(30.0, hello)
t.start() # after 30 seconds, "hello, world" will be printed
