Python Forum

I am trying to send a email using Python. I have an account on Gmail and a proven password (which I will say as ABCD00). When I try to send the email, I get an error:

import smtplib, ssl

sender_email = "my@gmail"
receiver_email = "[email protected]"
message = "Hello, world"

ctx=ssl.create_default_context()
with smtplib.SMTP_SSL("smtp.gmail.com", 465, context=ctx) as server:
   server.login("[email protected]", "ABCD00")
   server.sendmail(sender_email, receiver_email, message)

But I get:

Error:
Traceback (most recent call last):
  File "./emailer.py", line 15, in <module>
    server.login("[email protected]", "ABCD00")
  File "/usr/lib/python3.5/smtplib.py", line 729, in login
    raise last_exception
  File "/usr/lib/python3.5/smtplib.py", line 720, in login
    initial_response_ok=initial_response_ok)
  File "/usr/lib/python3.5/smtplib.py", line 641, in auth
    raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted. Learn more at\n5.7.8  https://support.google.com/mail/?p=BadCredentials y22sm7196990ejf.108 - gsmtp')

Same thing if I use my as user name. Yet, I can log in with [email protected] and ABCD00 on the browser.
What is the error? How can I send an email with Python?
Thank you

Go into your google account in Safety turn on Access to less secure apps.
Then try again.

Now that I have removed the safeties from Gmail, I can send the email:

import smtplib, ssl

sender_email = "me@gmail"
receiver_email = "[email protected]"
message = "Hello, world"

print("sending email")
ctx=ssl.create_default_context()
with smtplib.SMTP_SSL("smtp.gmail.com", 465, context=ctx) as server:
    server.login("me", password)
    server.sendmail(sender_email, receiver_email, message)
print("sent")

Probably there is a better way, in particular without the use of SSL (but when I tried smtplit.SMTP only, it did not work.

My question now is: how can I add a subject to the email?
Thank you
