We can create an email message and attach Python's python-logo.gif file with the email message. Then, this message is sent from a Google account to a different account.

Listing 4.6 shows us how to send an email from your Google account:

def send_email(sender, recipient): 
    """ Send email message """ 
    msg = MIMEMultipart()

    files = filter(gifsearch.search, files) 
    for filename in files: 
        path = os.path.join(os.getcwd(), filename) 
        if not os.path.isfile(path): 
            continue 
        img = MIMEImage(open(path, 'rb').read(), _subtype="gif") 
        img.add_header('Content-Disposition', 'attachment',
        filename=filename) 
        msg.attach(img)

    session = smtplib.SMTP(SMTP_SERVER, SMTP_PORT) 
    session.ehlo() 
    session.starttls() 
    session.ehlo 
    password = getpass.getpass(prompt="Enter your Google password: ")  
    session.login(sender, password) 
    session.sendmail(sender, recipient, msg.as_string()) 
    print ("Email sent.") 
    session.quit()

Running the following script outputs the success of sending an email to any email address if you provide your Google account details correctly. After running this script, you can check your recipient email account to verify that the email is actually sent:

$ python 5_6_send_email_from_gmail.py --sender=<USERNAME>@gmail.com -recipient=<USER>@<ANOTHER_COMPANY.com>
Enter you Google password: 
Email sent.
