Hassbian and Python

I decided to make the jump to Hassbian from the AIO install to get ahead of the Python deprecation, and just have a quick question. When I run

python -V

in either the root or virtual env, i get Python 2.7.13 back. I was expecting at least 3.5. Should I be worried?

Nevermind… I forgot activate the virtual env. Once activated, showing 3.5.3
