python send file with email code example

Example 1: send gmail email with attachment using python

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
mail_content = '''Hello,
This is a test mail.
In this mail we are sending some attachments.
The mail is sent using Python SMTP library.
Thank You
'''
#The mail addresses and password
sender_address = '[email protected]'
sender_pass = 'xxxxxxxx'
receiver_address = '[email protected]'
#Setup the MIME
message = MIMEMultipart()
message['From'] = sender_address
message['To'] = receiver_address
message['Subject'] = 'A test mail sent by Python. It has an attachment.'
#The subject line
#The body and the attachments for the mail
message.attach(MIMEText(mail_content, 'plain'))
attach_file_name = 'TP_python_prev.pdf'
attach_file = open(attach_file_name, 'rb') # Open the file as binary mode
payload = MIMEBase('application', 'octate-stream')
payload.set_payload((attach_file).read())
encoders.encode_base64(payload) #encode the attachment
#add payload header with filename
payload.add_header('Content-Decomposition', 'attachment', filename=attach_file_name)
message.attach(payload)
#Create SMTP session for sending the mail
session = smtplib.SMTP('smtp.gmail.com', 587) #use gmail with port
session.starttls() #enable security
session.login(sender_address, sender_pass) #login with mail_id and password
text = message.as_string()
session.sendmail(sender_address, receiver_address, text)
session.quit()
print('Mail Sent')

Example 2: 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()
