Send an email with a gmail account using python 3

send_an_email.py

# smtplib module send mail

import smtplib

TO = '[email protected]'
SUBJECT = 'TEST MAIL'
TEXT = 'Here is a message from python.'

# Gmail Sign In
gmail_sender = '[email protected]'
gmail_passwd = 'password'

server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login(gmail_sender, gmail_passwd)

BODY = '\r\n'.join(['To: %s' % TO,
                    'From: %s' % gmail_sender,
                    'Subject: %s' % SUBJECT,
                    '', TEXT])

try:
    server.sendmail(gmail_sender, [TO], BODY)
    print ('email sent')
except:
    print ('error sending mail')

server.quit()

`import smtplib
li = ["[email protected]", "[email protected]"] #list of email_id to send the mail

for i in range(len(li)):
s = smtplib.SMTP('smtp.gmail.com', 587)
s.starttls()
s.login("sender_email_id", "sender_email_id_password")
message = "Message_you_need_to_send"
s.sendmail("sender_email_id", li[i], message)
s.quit() `

This is regarding multiple emails at once:
---- List of emials:
TO = "[email protected],[email protected],[email protected]"

---- change this line :
"s.sendmail("sender_email_id", li[i], message)"

---- For this line:
s.sendmail(sender_email_id, TO.split(","), message)

That helped a lot. Many thanks. =]

How to add Bcc?

Done I found a Way:

BODY = '\r\n'.join([ 'From: %s' % gmail_sender, 'Subject: %s' % SUBJECT, '', TEXT])
