廖老师后面几个模块的引入没有写进来，我google了一下找到了。现在把完整代码附在下面，希望能帮到后面的同学。
一开始完全没看懂那个MIME是什么东西，查了一下是一种互联网标准，全名是“多用途互联网邮件扩展（MIME，Multipurpose Internet Mail Extensions）”，可以使邮件支持更多形式的内容。大概这个样子把。

#! /usr/bin/python3
# encoding: utf-8
from email.mime.text import MIMEText
from email.header import Header
from email.utils import parseaddr, formataddr
from email.mime.multipart import MIMEMultipart, MIMEBase
from email import encoders
import smtplib


def _format_addr(s):
    name, addr = parseaddr(s)
    return formataddr((Header(name, 'utf-8').encode(), addr))

from_addr = 'xxxxxxxxxx@sina.com'
password = 'xxxxxxxxx'
to_addr = 'xxxxxxxxxx@163.com'
smtp_server = 'smtp.sina.com'

msg = MIMEMultipart()
msg['From'] = _format_addr('Python爱好者<%s>' % from_addr)
msg['To'] = _format_addr('管理员<%s>' % to_addr)
msg['Subject'] = Header('来自管理员的问候...', 'utf-8').encode()
msg.attach(MIMEText(
    '<html><body><p>hello, send by Vincent...</p><br><p><img src="cid:0"></p></body></html>', 'html', 'utf-8'))

with open('/home/vincent/图片/加缪.jpg', 'rb') as f:
    mime = MIMEBase('image', 'jpg', filename='jiamiu.jpg')
    mime.add_header('Content-Disposition', 'attachment', filename='jiamiu.jpg')
    mime.add_header('Content-ID', '<0>')
    mime.add_header('X-Attachment-Id', '0')
    mime.set_payload(f.read())
    encoders.encode_base64(mime)
    msg.attach(mime)

server = smtplib.SMTP(smtp_server, 25)
server.starttls()
server.set_debuglevel(1)
server.login(from_addr, password)
server.sendmail(from_addr, [to_addr], msg.as_string())
server.quit()

这几个代码我没懂干什么用的，谁帮忙解释一下。谢谢。

mime.add_header('Content-Disposition', 'attachment', filename='jiamiu.jpg')
    mime.add_header('Content-ID', '<0>')
    mime.add_header('X-Attachment-Id', '0')
