模块 schedule 定时任务

schedule模块实现定时任务

一、官方示例

import schedule
import time 

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

schedule.every(10).minutes.do(job)
schedule.every().hour.do(job)
schedule.every().day.at("10:30").do(job)
schedule.every(5).to(10).days.do(job)
schedule.every().monday.do(job)
schedule.every().wednesday.at("13:15").do(job) 

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

二、多线程解决多任务串行执行任务的延迟问题

未使用多线程

import datetime
import schedule
import time 

def job1():
    print("I'm working for job1")
    time.sleep(2)
    print("job1:", datetime.datetime.now())

def job2():
    print("I'm working for job2")
    time.sleep(2)
    print("job2:", datetime.datetime.now()) 

def run():
    schedule.every(10).seconds.do(job1)
    schedule.every(10).seconds.do(job2)     

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

使用多线程

import datetime
import schedule
import threading
import time

def job1():
    print("I'm working for job1")
    time.sleep(2)
    print("job1:", datetime.datetime.now())

def job2():
    print("I'm working for job2")
    time.sleep(2)
    print("job2:", datetime.datetime.now())

def job1_task():
    threading.Thread(target=job1).start()

def job2_task():
    threading.Thread(target=job2).start()

def run():
    schedule.every(10).seconds.do(job1_task)
    schedule.every(10).seconds.do(job2_task)

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