python定时任务，定时实现发邮件，定时备份

python定时任务主要模块sched，还有ApScheduler还可以通过其他方式实现定时任务，而ApScheduler是需要pip命令来下载，用sched更方便实现一些

定时发邮件

import sched
import time
import smtplib
from email.mime.text import MIMEText
def send_email(subject, message, from_addr, to_addr, smtp_server):
    # 邮件的主体信息
    email = MIMEText(message)
    email['Subject'] = subject
    email['From'] = from_addr
    email['To'] = to_addr
    # 发邮件
    with smtplib.SMTP(smtp_server) as server:
        server.send_message(email)
def send_scheduled_email(subject, message, from_addr, to_addr, smtp_server, scheduled_time):
    # 创建定时任务的示例
    scheduler = sched.scheduler(time.time, time.sleep)
    # 定时邮件
    scheduler.enterabs(scheduled_time, 1, send_email, argument=(subject, message, from_addr, to_addr, smtp_server))
    # 开启定时器
    scheduler.run()
subject = 'Test Email'
message = 'This is a test email'
from_addr = 'test@example.com'
to_addr = 'test@example.com'
smtp_server = 'smtp.test.com'
scheduled_time = time.time() + 60*60 # 一小时后执行程序，设置定时时间发送
send_scheduled_email(subject, message, from_addr, to_addr, smtp_server, scheduled_time)    

定时备份

import sched
import time
import shutil
def backup_files():
    source = '备份的路径'
    destination = '备份到路径'
    shutil.copytree(source, destination)
def schedule_backup():
    # 创建新的定时器
    scheduler = sched.scheduler(time.time, time.sleep)
    # 备份程序在每天的1点来执行
    backup_time = time.strptime('01:00:00', '%H:%M:%S')
    backup_event = scheduler.enterabs(time.mktime(backup_time), 1, backup_files, ())
    # 开启定时任务
    scheduler.run()
schedule_backup()
