        print('Email sent!')
    except Exception as exception:
        print("Error: %s!\n\n" % exception)

How can I attach the helloword.txt file in this email? This code is working fine, I just want to send an attachment along with it. This code lets me me send the body without any attachment. Also, how do I encrypt the key.txt file which store email address and password, and to send email it it requires the password to be entered (diff pass)?

For encrypting password , https://stackoverflow.com/questions/27335726/how-do-i-encrypt-and-decrypt-a-string-in-python link might help — PN7, May 31 '20 at 16:16

You need to use the 'MIMEMultipart' module to attach files.

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

mail = MIMEMultipart()
mail["Subject"] = sent_subject
mail["From"] = sent_from
mail["To"] = sent_to
mail.attach(MIMEText(sent_body,'html'))

ctype, encoding = mimetypes.guess_type(_file)
maintype, subtype = ctype.split('/', 1)
fp = open("/path/to/attachment/file.txt")
# If file mimetype is video/audio use respective email.mime module. 
# Here assuming 'maintype' == 'text' we will use MIMEText
msg = MIMEText(fp.read(), _subtype=subtype)
fp.close()
filename = os.path.basename(_file)
msg.add_header('Content-Disposition', 'attachment', filename=filename)
mail.attach(msg)


server.sendmail(sent_from, sent_to, mail.as_string())

Hi, mail.attach[MIMEText(sent_body,'html')] should be mail.attach(MIMEText(sent_body,'html')) – PN7 Jun 06 '20 at 05:58

'mimetypes' is a python module. Just 'import mimetypes' – PN7 Jun 13 '20 at 14:51

    smtpObj.sendmail(fromaddr, sendto , text)
    smtpObj.quit()    # attach the instance 'p' to instance 'msg'

here is perfect working code for sending email
