Is there something that this handles that pip/requirements doesn't? Python has always been a breeze for this situation.

Poetry comes with an exhaustive and efficient dependency resolver which pip does not have.

It's also a packaging tool, which means you can build and publish packages with (on PyPI for instance).

And finally, it always creates a virtualenv for each project so that you always work isolated from the global Python installation.
