[Python] AttributeError: 'module' object has no attribute '_create_unverified_context'

I got the following error

AttributeError: 'module' object has no attribute '_create_unverified_context'.
​

I'm using Python 3.4.2 .

My code:

import ssl
ssl._create_default_https_context = ssl._create_unverified_context


When I run this code, the error happens._create_unverified_context can be used in Python 3.4.2, so I really cannot understand why this error happens. How should I fix this? Traceback says
