Poetry: Python packaging and dependency management made easy Poetry helps you declare, manage and install dependencies of Python projects, ensuring you have the right stack everywhere. Poetry replaces setup.py, requirements.txt, setup.cfg, MANIFEST.in and Pipfile with a simple pyproject.toml based project format. [build-system] requires = ["poetry-core>=2.0.0,<3.0.0"] build-backend = "poetry.core.masonry.api" [project] name = "my-package" version = "0.1.0" description = "The description of the package" readme = "README.md" license = "MIT" license-files = ["LICENSE"] # No Python upper bound for package metadata requires-python = ">=3.9" authors = [ { name = "Sébastien Eustace", email = "sebastien@eustace.io" }, ] # Keywords (translated to tags on the package index) keywords = ["packaging", "poetry"] dependencies = [ # equivalent to ^3.8.1 with semver constraints "aiohttp (>=3.8.1,<4.0.0)", # dependency with extras "requests[security] (>=2.28,<3.0)", # version-specific dependency with prereleases allowed (see below) "tomli (>=2.0.1,<3.0.0) ; python_version < '3.11'", # git dependency with branch specified "cleo @ git+https://github.com/python-poetry/cleo.git@main", ] [project.urls] repository = "https://github.com/python-poetry/poetry" homepage = "https://python-poetry.org" # Scripts are easily expressed [project.scripts] my_package_cli = "my_package.console:run" [project.optional-dependencies] # optional dependency to be installed via 'poetry install -E my-extra' my-extra = ["pendulum (>=3.1.0,<4.0.0)"] [tool.poetry.dependencies] # Python upper bound for locking python = ">=3.9,<4.0" # Version-specific dependencies with prereleases allowed tomli = { allow-prereleases = true } # Dependency groups are supported for organizing your dependencies [dependency-groups] dev = ["pytest (>=7.1.2,<8.0.0)", "pytest-cov (>=3.0,<4.0)"] docs = ["Sphinx (>=5.1.1,<6.0.0)"] # ...and can be installed only when explicitly requested # via 'poetry install --with docs' [tool.poetry.group.docs] optional = true # Alternatively, you can use Poetry specific syntax # to specify dependency groups [tool.poetry.group.lint] optional = true [tool.poetry.group.lint.dependencies] ruff = ">=0.10.0" Installation Poetry supports multiple installation methods, including a simple script found at install.python-poetry.org. For full installation instructions, including advanced usage of the script, alternate install methods, and CI best practices, see the full installation documentation. Documentation Documentation for the current version of Poetry (as well as the development branch and recently out of support versions) is available from the official website. Contribute Poetry is a large, complex project always in need of contributors. For those new to the project, a list of suggested issues to work on in Poetry and poetry-core is available. The full contributing documentation also provides helpful guidance.
