本篇文章主要介绍了详解python调度框架APScheduler使用，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

最近在研究python调度框架APScheduler使用的路上，那么今天也算个学习笔记吧！# coding=utf-8

Demonstrates how to use the background scheduler to schedule a job that executes on 3 second

intervals.

time.sleep(2) #其他任务是独立的线程执行

print('sleep!')

scheduler.shutdown()

print('Exit The Job!')

非阻塞调度，在指定的时间执行一次# coding=utf-8
