How I would start using python 3.6 in my virtual environment

How would i set up virtual environment using python 3.6

what have you tried?

mkvirtualenv --python=/usr/bin/python3.6 my-venv-name

should do it...

so if i create virtual environment with the name venv, it will be something like: --python=/usr/bin/python3.6 venv

Tried that and it doesn't work

once you've created a virtualenv you can't change its version of python. you need to delete it and create a new one...
