Poetry is a Python tool to handle dependency installation as well as building and packaging of Python packages. Do not use this tag for poems written in Python language since this is off-topic on Stack Overflow.

What are the advantages of Poetry compared to other types of package management? From the documentation:

Packaging systems and dependency management in Python are rather convoluted and hard to understand for newcomers. Even for seasoned developers it might be cumbersome at times to create all files needed in a Python project: setup.py, requirements.txt, setup.cfg, MANIFEST.in and the newly added Pipfile.

So I wanted a tool that would limit everything to a single configuration file to do: dependency management, packaging and publishing.

It takes inspiration in tools that exist in other languages, like Composer (PHP) or Cargo (Rust).

And, finally, there is no reliable tool to properly resolve dependencies in Python, so I started poetry to bring an exhaustive dependency resolver to the Python community.
