Gmail SMTP身份验证始终失败

Question

I created this software in python 3

import smtplib
TO = '[e-mail]'
SUBJECT = 'Text subject of the mail'
TEXT = 'Text of the mail'

gmail_sender = '[e-mail]'
gmail_passwd = 'password'
server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login(gmail_sender, gmail_passwd)
BODY = '
'.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()

The first day the software worked well but now I always have an authentification error from gmail :

   smtplib.SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted. Learn more at
5.7.8  https://support.google.com/mail/?p=BadCredentials o81-v6sm9180362wmo.38 - gsmtp')

What I did already is :

I desactivated the unlock captchar from this link :

https://accounts.google.com/DisplayUnlockCaptcha

and I have enabled the less secure apps from this link:

https://www.google.com/settings/security/lesssecureapps

But still the same, I can't send an e-mail anymore. It doesn't seems that there's a Python software problem because I wrote the same software in Go and I still receive the same error.

It’s solved. My login was wrong.
