Re: Best Practices python virtualenv

Thanks for all the responses but it seems an alternate solution presented by
another user in a direct reply is to use python3 - m venv. Basically using the
venv built in to python3 as opposed to the legacy method of py-virtualenv that I
typically only have to use for older python 2 code bases.

Thanks all for the replies.
