poetry is a Python dependency management and packaging tool that uses pyproject.toml as its single configuration file. It handles dependency resolution, virtual environment management, building, and publishing packages to PyPI.
Poetry creates isolated virtual environments for each project and uses a lock file (poetry.lock) to ensure reproducible installations across different machines. Key commands include install (install dependencies), add/remove (manage dependencies), run (execute in venv), and shell (activate venv).
