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)
