Python Path is Isolated?

To check we've done everything properly and islolated the old system python with a virtual environment created by pyenv we can:

which python which python3 which pip

You should see paths like:

~/.pyenv/shims/python ~/.pyenv/shims/python3 ~/.pyenv/shims/pip

Not anything under `/usr/bin/` — that’s the system Python you want to leave alone.
