Python定时执行任务 Python实现定时执行任务的三种方式简单示例
YaoShuangQisBlogs 人气:0本文实例讲述了Python实现定时执行任务的三种方式。分享给大家供大家参考,具体如下:
1.定时任务代码
#!/user/bin/env python # @Time :2018/6/7 16:31 # @Author :PGIDYSQ #@File :PerformTaskTimer.py #定时执行任务命令 import time,os,sched schedule = sched.scheduler(time.time,time.sleep) def perform_command(cmd,inc): os.system(cmd) print('task') def timming_exe(cmd,inc=60): schedule.enter(inc,0,perform_command,(cmd,inc)) schedule.run() print('show time after 2 seconds:') timming_exe('echo %time%',2)
2.周期性执行任务
#!/user/bin/env python # @Time :2018/6/7 16:31 # @Author :PGIDYSQ #@File :PerformTaskTimer.py import time,os,sched schedule = sched.scheduler(time.time,time.sleep) def perform_command(cmd,inc): #在inc秒后再次运行自己,即周期运行 schedule.enter(inc, 0, perform_command, (cmd, inc)) os.system(cmd) def timming_exe(cmd,inc=60): schedule.enter(inc,0,perform_command,(cmd,inc)) schedule.run()#持续运行,直到计划时间队列变成空为止 print('show time after 2 seconds:') timming_exe('echo %time%',2)
3.循环执行命令
#!/user/bin/env python # @Time :2018/6/7 16:31 # @Author :PGIDYSQ #@File :PerformTaskTimer.py import time,os def re_exe(cmd,inc = 60): while True: os.system(cmd) time.sleep(inc) re_exe("echo %time%",5)
希望本文所述对大家Python程序设计有所帮助。
