I am trying to write a script which can send email from my gmail account. However I am getting error mentioned below. I am using windows10 64bit. It looks like a SSL error but unable to find any solution for this -

import smtplib
smtpObj = smtplib.SMTP('smtp.gmail.com', 587)

**Traceback (most recent call last):
