- Poetry is a tool for managing Python project dependencies and virtual environments.
- Poetry provides deterministic dependencies and simplifies building, packaging, and publishing projects to PyPI.
- Poetry uses a custom installer and centralizes virtual environments in a cache directory.
- Creating a Poetry project involves using `poetry new <project_name>`, which scaffolds the project with `pyproject.toml`, `README.rst`, tests, and a `src` directory.
- Poetry manages virtual environments in a centralized cache, unlike traditional methods that place them in the project directory.
- Dependencies can be added generally or as part of dependency groups using `poetry add`.
- Poetry generates a `poetry.lock` file to ensure consistent dependency versions across installations.
- Removing a Poetry virtual environment requires using `poetry env remove python`.
- Poetry has an experimental feature for managing Python installations, but it's recommended to use other tools like `pyenv` for general Python version management.
