python send file as an attachment code example

Example 1: how to send doc using python smtp

# Python code to illustrate Sending mail with attachments 
# from your Gmail account  
  
# libraries to be imported 
import smtplib 
from email.mime.multipart import MIMEMultipart 
from email.mime.text import MIMEText 
from email.mime.base import MIMEBase 
from email import encoders 
   
fromaddr = "EMAIL address of the sender"
toaddr = "EMAIL address of the receiver"
   
# instance of MIMEMultipart 
msg = MIMEMultipart() 
  
# storing the senders email address   
msg['From'] = fromaddr 
  
# storing the receivers email address  
msg['To'] = toaddr 
  
# storing the subject  
msg['Subject'] = "Subject of the Mail"
  
# string to store the body of the mail 
body = "Body_of_the_mail"
  
# attach the body with the msg instance 
msg.attach(MIMEText(body, 'plain')) 
  
# open the file to be sent  
filename = "File_name_with_extension"
attachment = open("Path of the file", "rb") 
  
# instance of MIMEBase and named as p 
p = MIMEBase('application', 'octet-stream') 
  
# To change the payload into encoded form 
p.set_payload((attachment).read()) 
  
# encode into base64 
encoders.encode_base64(p) 
   
p.add_header('Content-Disposition', "attachment; filename= %s" % filename) 
  
# attach the instance 'p' to instance 'msg' 
msg.attach(p) 
  
# creates SMTP session 
s = smtplib.SMTP('smtp.gmail.com', 587) 
  
# start TLS for security 
s.starttls() 
  
# Authentication 
s.login(fromaddr, "Password_of_the_sender") 
  
# Converts the Multipart msg into a string 
text = msg.as_string() 
  
# sending the mail 
s.sendmail(fromaddr, toaddr, text) 
  
# terminating the session 
s.quit()

Example 2: how to add a file to an email in python

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email import Encoders


SUBJECT = "Email Data"

msg = MIMEMultipart()
msg['Subject'] = SUBJECT 
msg['From'] = self.EMAIL_FROM
msg['To'] = ', '.join(self.EMAIL_TO)

part = MIMEBase('application', "octet-stream")
part.set_payload(open("text.txt", "rb").read())
Encoders.encode_base64(part)

part.add_header('Content-Disposition', 'attachment; filename="text.txt"')

msg.attach(part)

server = smtplib.SMTP(self.EMAIL_SERVER)
server.sendmail(self.EMAIL_FROM, self.EMAIL_TO, msg.as_string())
