发邮件是一种很常见的操作，本篇主要介绍一下如何用python实现自动发件。

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.header import Header
from email.mime.image import MIMEImage
import time
mail_host="smtp.126.com"
mail_user="xxx@126.com"
mail_pass="******"#注意如果邮箱开启了授权码，此处要填写授权码，否则会报smtplib.SMTPAuthenticationError: (535, b"Error: authentication failed")
sender="xxx@126.com"
receiver = ["邮箱1","邮箱2"]#群发邮件
for i in range(n):#自定义循环发多少遍
try:
        message = MIMEMultipart()
        message["From"] = Header(sender)
        message["To"] = ",".join(receiver)
        message["Subject"] = Header("主题", "utf-8").encode()#主题
        message.attach(MIMEText("正文", "plain", "utf-8"))#正文
"""
        定附件
"""
        att = MIMEText(open(r"C:UsersAdministratorDesktop1.txt").read(), "base64", "utf-8")
        att["Content-Type"] = "application/octet-stream"
            att.add_header("Content-Disposition", "attachment", filename="1.txt")#这一步可避免文件不能正常打开
        message.attach(att)
"""
        构造图片（以附件形式上传）
"""
        image = MIMEImage(open(r"C:UsersAdministratorDesktop1.jpg", "rb").read())
        image.add_header("Content-ID", "<image1>")#可避免图片不能正常打开
        image["Content-Disposition"] = "attachment; filename="picture.jpg""
        message.attach(image)
"""
           发送邮件
"""
        smtp = smtplib.SMTP_SSL(host=mail_host)
        smtp.connect(host=mail_host, port=465)
        smtp.login(mail_user, mail_pass)
        smtp.sendmail(sender, message["To"].split(","), message.as_string())
print("在%s第" % ctime(), str(i+1), "封邮件发送")
        smtp.quit()
except smtplib.SMTPException as e:
raise e
