SMTP acting weirdly

Question

I'm trying to use SMTPLIB in python to send a message, however I get an error message. I'm positive that the e-mail and passwords used are correct. I have tried to send this with and without signing in via web browser. I have allowed less secure sources from the SENDERS email as the following stackoverflow article states : Error sending email: raise SMTPAuthenticationError(code, resp). I have substituted words instead of actual emails and passwords in the below code:

import smtplib

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login("senderemail", "senderemailpassword")

msg = "Hello!"
server.sendmail("senderemail", "recieveremail", msg)
server.quit()

Error message:

Traceback (most recent call last):
  File "D:\Hussain\Hussain's computing\Python\emailingtest.py", line 5, in <module>
    server.login("senderemail", "senderpassword")

It would be very helpful if someone could fix my code.

Google blocks by default any attempts of login from script/application which does not use modern security standards. However you can change that settings on: https://www.google.com/settings/security/lesssecureapps.

Thank you, but I've tried that as mentioned in the question – Hussain Hammad Aug 30 '18 at 11:36
It is possible also that google is displaying captcha. Are you sure you turned mentioned setting to ON not OFF? – mcjay Aug 30 '18 at 11:42
No, I haven't, how do I stop that? – Hussain Hammad Aug 30 '18 at 11:44
https://accounts.google.com/DisplayUnlockCaptcha - here you can change your settings, after changing that you should wait few minutes before re-running the script. – mcjay Aug 30 '18 at 11:54
