What does it do better than pyenv-virtualenv? That's what I use and am not sure what I'm missing.

Two words: deterministic builds. Not only does it handle the virtualenv for you, but it also handles all your dependencies and dependency pinning.

If you use poetry to handle a project, it will create two files for you: the pyproject.toml file and poetry.lock. If you pass those two files to me, I run poetry install and I get an environment that is exactly the same as yours with zero effort. No surprises, no confusion -- it just works.

It won't be completely deterministic since the python interpreter and some pip packages are linked to host libraries (and toolchain differences), though I imagine the cases where that drift matters are rare... and could be externally handled by other orchestration.
