1. import smtplib 
2. from email.mime.multipart import MIMEMultipart 
3. from email.mime.text import MIMEText 
4. from email.mime.base import MIMEBase 
5. from email import encoders 
6. mail_content = '''Hello, 
7. This is a test mail. 
8. In this mail we are sending some attachments. 
9. The mail is sent using Python SMTP library. 
10. Thank You 
11. ''' 
12. #The mail addresses and password 
13. sender_address = '[email protected]' 
14. sender_pass = 'xxxxxxxx' 
15. receiver_address = '[email protected]' 
16. #Setup the MIME 
17. message = MIMEMultipart() 
18. message['From'] = sender_address 
19. message['To'] = receiver_address 
20. message['Subject'] = 'A test mail sent by Python. It has an attachment.' 
21. #The subject line 
22. #The body and the attachments for the mail 
23. message.attach(MIMEText(mail_content, 'plain')) 
24. attach_file_name = 'TP_python_prev.pdf' 
25. attach_file = open(attach_file_name, 'rb') # Open the file as binary mode 
26. payload = MIMEBase('application', 'octate-stream') 
27. payload.set_payload((attach_file).read()) 
28. encoders.encode_base64(payload) #encode the attachment 
29. #add payload header with filename 
30. payload.add_header('Content-Decomposition', 'attachment', filename=attach_file_name) 
31. message.attach(payload) 
32. #Create SMTP session for sending the mail 
33. session = smtplib.SMTP('smtp.gmail.com', 587) #use gmail with port 
34. session.starttls() #enable security 
35. session.login(sender_address, sender_pass) #login with mail_id and password 
36. text = message.as_string() 
37. session.sendmail(sender_address, receiver_address, text) 
38. session.quit() 
39. print('Mail Sent')
