python中使用schedule模块定时执行任务

python中有一个轻量级的定时任务调度的库:schedule。他可以完成每分钟,每小时,每天,周几,特定日期的定时任务。因此十分方便我们执行一些轻量级的定时任务.

代码如下:

 1 import schedule
 2 import time
 3  
 4 def job(name):
 5     print("her name is : ", name)
 6  
 7 name = "longsongpong"
 8 schedule.every(10).minutes.do(job, name)
 9 schedule.every().hour.do(job, name)
10 schedule.every().day.at("10:30").do(job, name)
11 schedule.every(5).to(10).days.do(job, name)
12 schedule.every().monday.do(job, name)
13 schedule.every().wednesday.at("13:15").do(job, name)
14  
15 while True:
16     schedule.run_pending()
17     time.sleep(1)
  • 每隔十分钟执行一次任务
  • 每隔一小时执行一次任务
  • 每天的10:30执行一次任务
  • 每隔5到10天执行一次任务 
  • 每周一的这个时候执行一次任务
  • 每周三13:15执行一次任务
  • run_pending:运行所有可以运行的任务

schedule方法是串行的,也就是说,如果各个任务之间时间不冲突,那是没问题的;如果时间有冲突的话,会串行的执行命令

代码如下:

 1 import schedule
 2 import time
 3 import threading
 4  
 5 def job():
 6     print("I'm working... in job1  start")
 7     time.sleep(15)
 8     print("I'm working... in job1  end")
 9  
10 def job2():
11     print("I'm working... in job2")
12  
13 schedule.every(10).seconds.do(job)
14 schedule.every(10).seconds.do(job2)
15  
16 while True:
17     schedule.run_pending()
18     time.sleep(1)

结果如下:

I’m working… in job1 start 
I’m working… in job1 end 
I’m working… in job2

如果要多线程并发运行

代码如下:

 1 import schedule
 2 import time
 3 import threading
 4  
 5 def job():
 6     print("I'm working... in job1  start")
 7     time.sleep(15)
 8     print("I'm working... in job1  end")
 9  
10 def job2():
11     print("I'm working... in job2")
12    
13 def run_threaded(job_func):
14      job_thread = threading.Thread(target=job_func)
15      job_thread.start()
16  
17  schedule.every(10).seconds.do(run_threaded,job)
18  schedule.every(10).seconds.do(run_threaded,job2)
19  
20  
21 while True:
22     schedule.run_pending()
23     time.sleep(1)

结果如下:

1 I'm working... in job1  start
2 I'm working... in job2
3 I'm working... in job1  start
4 I'm working... in job2
5 I'm working... in job1  end
6 I'm working... in job1  start
7 I'm working... in job2
