pyenv

pyenv is a command line tool for installing and switching between different versions of the Python interpreter. It is based on a rbenv, a tool for managing Ruby interpreters.

pyenv allows the user to install many different versions of the CPython interpreter (e.g. Python 2.7.18, 3.12.0), Anaconda/Miniconda, PyPy, and others.

pyenv users can then select a version to run globally, for a particular user, or for a particular project/folder.
