Pyenv! Let the OS have its own version and work on whatever version you want, whenever.

You are 100% right, that’s why we use virtual environments. Specifically we use poetry, which is fine.

Conda is, to the alternative already mentioned, a great way to keep different versions of python and it’s packages for each project!

On Linux, I’d just build my own Python binaries and make them available. But you can also use pyenv for the same thing if you’re ok with it.

Then, using poetry, I have different projects with isolated environments.
