怎么把python程序发给别人

可以将python编译成可执行文件发送，也可以采取打包的形式，将程序打包成压缩文件包后再发送。

python中如何实现发送邮件及附件功能的具体详解

思路如下：

1. 构造MIMEMultipart对象做为根容器

2. 构造MIMEText对象做为邮件显示内容并附加到根容器

3. 构造MIMEBase对象做为文件附件内容并附加到根容器

a. 读入文件内容并格式化

b. 设置附件头

4. 设置根容器属性

5. 得到格式化后的完整文本

6. 用smtp发送邮件

如何用Python发邮件

Python发送邮件简单的实例：

#!/usr/bin/python

# -*- coding: UTF-8 -*-

import smtplib

from email.mime.text import MIMEText

from email.header import Header

sender = ‘from@runoob.com’

receivers = [‘429240967@qq.com’] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱

# 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码

message = MIMEText(‘Python 邮件发送测试…’, ‘plain’, ‘utf-8’)

message[‘From’] = Header(“菜鸟教程”, ‘utf-8’)

message[‘To’] = Header(“测试”, ‘utf-8’)

subject = ‘Python SMTP 邮件测试’

message[‘Subject’] = Header(subject, ‘utf-8’)

try:

smtpObj = smtplib.SMTP(‘localhost’)

smtpObj.sendmail(sender, receivers, message.as_string())

print “邮件发送成功”

except smtplib.SMTPException:

print “Error: 无法发送邮件”

如何在python程序中发邮件

通过命令行发送邮件，功能强大

python ./mail -s $server -f $from -t $to -u $user -p $pass -S “$subject” -m “${mail_msg}” -F $file

Python 发送邮件可以添加附件：

#!/usr/bin/python

from email.MIMEText import MIMEText

from email.MIMEMultipart import MIMEMultipart

from email.MIMEBase import MIMEBase

from email import Utils, Encoders

import mimetypes, sys,smtplib,socket,getopt

self.from_addr=from_addr

self.to_addr=to_addr

self.username=user

self.password=passwd

def attachment(self,filename):

fd=open(filename,’rb’)

filename=filename.split(‘/’)

mimetype,mimeencoding=mimetypes.guess_type(filename[-1])

if (mimeencoding is None) or (mimetype is None):

mimetype=’application/octet-stream’

maintype,subtype=mimetype.split(‘/’)

if maintype==’text’:

retval=MIMEText(fd.read(), _subtype=subtype, _charset=’utf-8′)

else:

retval=MIMEBase(maintype,subtype)

retval.set_payload(fd.read())

Encoders.encode_base64(retval)

retval.add_header(‘Content-Disposition’,’attachment’,filename=filename[-1])

fd.close()

return retval

def msginfo(self,msg,subject,filename):

# message = “””Hello, ALL

#This is test message.

#–Anonymous”””

message=msg

msg=MIMEMultipart()

msg[‘To’] = self.to_addr

msg[‘From’] = ‘sa ‘+self.from_addr+”

msg[‘Date’] = Utils.formatdate(localtime=1)

msg[‘Message-ID’] = Utils.make_msgid()

if subject:

msg[‘Subject’] = subject

if message:

body=MIMEText(message,_subtype=’plain’)

msg.attach(body)

#for filename in sys.argv[1:]:

if filename:

msg.attach(self.attachment(filename))

return msg.as_string()

def send(self,msg=None,subject=None,filename=None):

try:

s=smtplib.SMTP(self.mailserver)

try:

s.login(self.username,self.password)

except smtplib.SMTPException,e:

print “Authentication failed:”,e

sys.exit(1)

s.sendmail(self.from_addr,self.to_addr.split(‘,’),self.msginfo(msg,subject,filename))

except (socket.gaierror,socket.error,socket.herror,smtplib.SMTPException),e:

print “*** Your message may not have been sent!”

print e

sys.exit(2)

else:

print “Message successfully sent to %d recipient(s)” %len(self.to_addr)
