想了解Python发送以整个文件夹的内容为附件的邮件的教程的相关内容吗，在本文为您仔细讲解Python发送文件夹为附件的邮件的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：Python，下面大家一起来学习吧。

由于我经常需要备份文件夹下的内容到邮件里面，每个打开邮件，上传文件，发送，太过麻烦，其实每次发送的文件都是放在固定置的，只是邮件标题不同而已，于是用 python 为自己写了个发送文件到邮箱的小工具，在任意目录下执行该脚本，并指定邮件标，就将指定文件夹下的文件发送到邮箱中备份起来。

#!/usr/bin/env python
# coding: utf-8

from smtplib import SMTP, quotedata, CRLF, SMTPDataError
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email import Encoders
from sys import stderr, stdout
import os
import sys

class ExtendedSMTP(SMTP):
  def data(self, msg):
    self.putcmd("data")
    (code,repl)=self.getreply()
    if self.debuglevel > 0 : print >> stderr, "data:", (code, repl)
    if code != 354:
      raise SMTPDataError(code,repl)
    else:
      q = quotedata(msg)
      if q[-2:] != CRLF:
        q = q + CRLF
      q = q + "." + CRLF

      # begin modified send code
      chunk_size = 2048
      bytes_sent = 0

      while bytes_sent != len(q):
        chunk = q[bytes_sent:bytes_sent+chunk_size]
        self.send(chunk)
        bytes_sent += len(chunk)
        if hasattr(self, "callback"):
          self.callback(bytes_sent, len(q))
      # end modified send code

      (code,msg)=self.getreply()
      if self.debuglevel >0 : print>>stderr, "data:", (code,msg)
      return (code,msg)

def callback(progress, total):
  percent = 100. * progress / total
  stdout.write('\r')
  stdout.write("%s bytes sent of %s [%2.0f%%]" % (progress, total, percent))
  stdout.flush()
  if percent >= 100: stdout.write('\n')

def sendmail(subject):
  MAIL_FROM = 'mymail@qq.com'
  MAIL_TO = ['mymail@qq.com']
  BAK_DIR = '/path/to/bak/folder'

  msg = MIMEMultipart()
  msg['From'] = MAIL_FROM
  msg['Subject'] = subject

  msg.attach( MIMEText('test send attachment') )
  for filename in os.listdir(BAK_DIR):
    part = MIMEBase('application', "octet-stream")
    part.set_payload(open(os.path.join(BAK_DIR, filename),"rb").read() )
    Encoders.encode_base64(part)
    part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(filename))
    msg.attach(part)

  try:
    smtp = ExtendedSMTP()
    smtp.callback = callback
    smtp.connect('smtp.qq.com', 25)
    smtp.login('mymail', 'mypwd')
    smtp.sendmail(MAIL_FROM, MAIL_TO, msg.as_string())
    smtp.close()
    os.system('rm -f %s/*' % BAK_DIR)
  except Exception, e:
    print e

if __name__ == '__main__':
  if len(sys.argv) == 1:
    print 'Please specific a subject'
    print 'Usage: send_files <MAIL_SUBJECT>'
  else:
    sendmail(sys.argv[1])

安装：

配置好收件人，发件人，smtp地址，用户名，密码及要发送文件所在的路径。

将文件保存为 send_files，保存到 /usr/bin 下面。

然后设置文件权限为可执行：

$ chmod +x send_files

用法：

$ send_files '邮件标题'
