Gmail Error using smtplib

[DJ Fadereu]

Hello, can anyone help me with this? What am I doing wrong here?

(I've changed private info to yyyy/xxxxxx)
 I'm getting an authentication error while using a standard script
Gmail:
--------------------------SCRIPT-----------------------------
import smtplib
from email.MIMEText import MIMEText

msg = MIMEText('Hello, this is fadereu...')
>From = 'yyyyyyyy at gmail.com'

msg['Subject'] = 'Hello'
msg ['From'] = 'ccccccc at gmail.com'
msg['To'] = 'fffd at xyz.com'

s = smtplib.SMTP('alt1.gmail-smtp-in.l.google.com')
s.set_debuglevel(1)
s.login('yyyyyyyyy at gmail.com','xxxxxxxxx')
s.sendmail(msg['From'], msg['To'], msg.as_string())
s.close()
----------------------------ERROR------------------------------
Traceback (most recent call last):
