In the previous section, we have seen how plain text messages can be sent by using the SMTP protocol. In this section, let us explore how to send attachments through e-mail messages. We can use our second example, in which we have sent an e-mail by using TLS, for this. While composing the e-mail message, in addition to adding a plain text message, include the additional attachment field.

In this example, we can use the MIMEImage type for the email.mime.image sub-module. A GIF type of image will be attached to the e-mail message. It is assumed that a GIF image can be found anywhere in the file system path. This file path is generally taken on the basis of the user input.

The following example shows how to send an attachment along with your e-mail message:

#!/usr/bin/env python3

import os
import getpass
import re
import sys
import smtplib

from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
