run some tasks which could look like CRON within linux/UNIX in python.
Here's a demo which run on ubuntu12.04
sudo pip install apscheduler
then
1) run a task at determained time 指定时间运行某个程序
2) run a task every period 指定周期运行某个程序
For 1)
here is a aps1.py
#coding: utf-8
#特定时间运行
from apscheduler.scheduler import Scheduler
sched = Scheduler()
sched.daemonic = False
def job_function(text):
print text
from datetime import datetime
#job = sched.add_date_job(job_function, datetime(2013, 10, 11, 02, 36, 00), ['Hello World'])
job = sched.add_date_job(job_function, datetime(2014, 10, 11, 02, 36, 00), ['Hello World'])
sched.start()
For 2)
here is a aps2.py
#coding: utf-8
# 间隔时间运行的
from apscheduler.scheduler import Scheduler
import time
sched = Scheduler()
sched.daemonic = False
def job_function():
print "wan si ni"
print time.strftime('%Y%m%d%H%M %S')
sched.add_interval_job(job_function, seconds=3)
sched.start()
