如何在Python异步执行的函数每60秒？ [英] How to execute a function asynchronously every 60 seconds in Python?

问题描述

我要执行Python的每60秒一个功能，但我不希望被阻止同时

I want to execute a function every 60 seconds on Python but I don't want to be blocked meanwhile.

我该怎么办呢异步？

import threading
import time

def f():
    print("hello world")
    threading.Timer(3, f).start()

if __name__ == '__main__':
    f()    
    time.sleep(20)

使用此code时，函数f每3秒执行20秒选定了time.time内。
在结束它提供了一个错误，我认为，这是因为threading.timer并没有被取消。

With this code, the function f is executed every 3 seconds within the 20 seconds time.time. At the end it gives an error and I think that it is because the threading.timer has not been canceled.

我怎样才能取消？

在此先感谢！

推荐答案

您可以尝试threading.Timer类：的 http://docs.python.org/library/threading.html#timer-objects 。

You could try the threading.Timer class: http://docs.python.org/library/threading.html#timer-objects.

import threading

def f():
    # do something here ...
    # call f() again in 60 seconds
    threading.Timer(60, f).start()

# start calling f now and every 60 sec thereafter
f()
