一个基于Python，提供类似Cron功能，并深受Java Quartz 影响的轻量级进程内任务调度框架。
Advanced Python Scheduler (APScheduler) is a light but powerful in-process task scheduler that lets you schedule jobs (functions or any python callables) to be executed at times of your choosing.
This can be a far better alternative to externally run cron scripts for long- running applications (e.g. web applications), as it is platform neutral and can directly access your application’s variables and functions.
The development of APScheduler was heavily influenced by the Quartz task scheduler written in Java. APScheduler provides most of the major features that Quartz does, but it also provides features not present in Quartz (such as multiple job stores).
