Python sends an instance of the Email method

In this paper, an example is presented to show how to implement the function of sending Email in Python. The specific implementation method is as follows:

The main function code is as follows:

#/usr/bin/env python
# -*- encoding=utf-8 -*-

import base64
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

class CCSendMail:
  def __init__(self,host="your.mailhost.com",username='fromuser@xxx.com',password='passwd'):
    self.__smtp=smtplib.SMTP(host)
    self.__subject=None
    self.__content=None
    self.__from=None
    self.__to=[]
    self.__style='html'
    self.__charset='gb2312'
    self.username = username
    self.password = password
    self.fromAlias='fromuser' # Sender alias 
    self.from2=''
    
  def close(self):
    try:
      self.__smtp.quit()
    except Exception ,e:
      pass  
  def setFromAlias(self,alias):
    self.fromAlias=alias
  def setStyle(self,style):
    self.__style = style
  def setFrom2(self,from2):
    self.from2=from2
    
  def setSubject(self,subject):
    self.__subject=subject
    
  def setContent(self,content):
    self.__content=content
    
  def setFrom(self,address):
    self.__from=address
    
  def addTo(self,address):
    self.__to.append(address)
    
  def setCharset(self,charset):
    self.__charset=charset
    
  def send(self):
    try:
      self.__smtp.set_debuglevel(1)
      
      #login if necessary
      if self.username and self.password:
        self.__smtp.login(self.username,self.password)
        
      msgRoot = MIMEMultipart('related')
      msgRoot['Subject'] = self.__subject
      aliasB6=base64.encodestring(self.fromAlias.encode(self.__charset))
      if len(self.from2)==0:
        msgRoot['From'] = "=?%s?B?%s?=%s"%(self.__charset,aliasB6.strip(),self.__from)
      else:
        msgRoot['From'] = "%s"%(self.from2)
      msgRoot['To'] = ";".join(self.__to)
      
      msgAlternative = MIMEMultipart('alternative')
      msgRoot.attach(msgAlternative)
      
      msgText = MIMEText(self.__content, self.__style,self.__charset)
      msgAlternative.attach(msgText)

      self.__smtp.sendmail(self.__from,self.__to,msgRoot.as_string())
      return True
    except Exception,e:
      print "Error ",e
      return False
    
  def clearRecipient(self):
    self.__to = []
  
  # Send an email to a single person 
  def sendHtml(self,address,title,content):
    self.setStyle('html')
    self.setFrom("<%s>"%self.username)
    if not isinstance(content,str):
      content = content.encode('gb18030')
    self.addTo(address)
    self.setSubject(title)
    self.setContent(content)
    ret = self.send()
    self.close()
    return ret
  
  # Mass email 
  def sendMoreHtml(self,addressList,title,content):
    self.setStyle('html')
    self.setFrom("<%s>"%self.username)
    if not isinstance(content,str):
      content = content.encode('gb18030')
    for address in addressList:
      self.addTo(address)
    self.setSubject(title)
    self.setContent(content)
    ret = self.send()
    self.close()
    return ret

# test 
def main():
  send=CCSendMail()
  send.sendHtml('touser@xxx.com',u' Email title ',u' Email content ')
  #send.sendMoreHtml([touser1@xx.com,touser2@xx.com],u' Email title ',u' Email content ')
 
if __name__=='__main__':
  main()

I hope the examples described in this article are helpful to your Python programming.
