Pew
Python Env Wrapper is a set of commands to manage multiple virtual environments. Pew can create, delete and copy your environments, using a single command to switch to them wherever you are, while keeping them in a single (configurable) location.
Python version management functionality is removed in Fedora 30+
Fedora provides excellent native means for using multiple different Python versions. One can install a non-default Python version, e.g. Python 3.6, by using:
sudo dnf install python36

Hence, removing the Python versions management from Pew itself should really be a non-issue. In addition, there is strong support upstream to either remove Pew's Python version management or replace it with pyenv: pew-org/pew#195.
