1.安裝schedule，安裝命令如下：

pip install schedule

2.以下為普通簡(jiǎn)單的例子：

import schedule
import time
 
def job():
    print("I'm working...")
 
# 每隔5分鐘執(zhí)行一次任務(wù)
schedule.every(5).minutes.do(job)
# 每隔一小時(shí)執(zhí)行一次任務(wù)
schedule.every().hour.do(job)
# 每天的10:30執(zhí)行一次任務(wù)
schedule.every().day.at("10:30").do(job)
# 每5-10分鐘執(zhí)行一次任務(wù)
schedule.every(5).to(10).minutes.do(job)
# 每周一的這個(gè)時(shí)候執(zhí)行一次任務(wù)
schedule.every().monday.do(job)
# 每周三的13:30執(zhí)行一次任務(wù)
schedule.every().wednesday.at("13:30").do(job)
# 每分鐘的這個(gè)時(shí)刻執(zhí)行一次任務(wù)
schedule.every().minute.at(":17").do(job)
# 如果job函數(shù)有有參數(shù)時(shí)，這么寫(xiě)
schedule.every(10).seconds.do(job，"參數(shù)") 

while True:
    # 啟動(dòng)服務(wù)
    run_pending() 
   #運(yùn)行所有可以運(yùn)行的任務(wù)
    schedule.run_pending()
    time.sleep(1)

3.schedule是串行執(zhí)行,如果時(shí)間重疊就會(huì)有重疊現(xiàn)象,但可以用多線程實(shí)現(xiàn)

import schedule
import time
import threading

def job():
    print("I'm working... in job1  start")
    time.sleep(15)
    print("I'm working... in job1  end")

def job2():
    print("I'm working... in job2")

def run_threaded(job_func):
     job_thread = threading.Thread(target=job_func)
     job_thread.start()
       #threading.Thread(target=loop,args=(i,loops[i]))

 schedule.every(10).seconds.do(run_threaded,job)
 schedule.every(10).seconds.do(run_threaded,job2)


while True:
    schedule.run_pending()
    time.sleep(1)

4.如果想要對(duì)線程的數(shù)量有所控制，則可以采用如下方法：

import Queue
import time
import threading
import schedule


def job():
    print("I'm working")


def worker_main():
    while 1:
        job_func = jobqueue.get()
        job_func()

jobqueue = Queue.Queue()

schedule.every(10).seconds.do(jobqueue.put, job)
schedule.every(10).seconds.do(jobqueue.put, job)
schedule.every(10).seconds.do(jobqueue.put, job)
schedule.every(10).seconds.do(jobqueue.put, job)
schedule.every(10).seconds.do(jobqueue.put, job)

worker_thread = threading.Thread(target=worker_main)
worker_thread.start()

while 1:
    schedule.run_pending()
    time.sleep(1)
