I recently used Pyenv to install an older version of Python on my system. The reason for this, is I wanted to create a Docker image using 3.8 slim-buster and I wanted to be explicit about the Python libraries I needed. By using Pyenv to install the same version of python as is used by slim-buster I was able to pip freeze my virtual env, and use the same version of libraries for the Docker image no problem. Oh the things I have to do in Python to avoid dependency hell
