The pyproject.toml file The tool.poetry section of the pyproject.toml file is composed of multiple sections. name The name of the package. Required This should be a valid name as defined by PEP 508. name = "my-package" version The version of the package. Required This should be a valid PEP 440 string. version = "0.1.0" Note If you would like to use semantic versioning for your project, please see here. description A short description of the package.

Configuration Poetry can be configured via the config command (see more about its usage here) or directly in the config.toml file that will be automatically created when you first run that command. This file can typically be found in one of the following directories: macOS: ~/Library/Application Support/pypoetry Windows: %APPDATA%\pypoetry For Unix, we follow the XDG spec and support $XDG_CONFIG_HOME. That means, by default ~/.config/pypoetry. Local configuration Poetry also provides the ability to have settings that are specific to a project by passing the --local option to the config command.

The pyproject.toml file The tool.poetry section of the pyproject.toml file is composed of multiple sections. package-mode Whether Poetry operates in package mode (default) or not. Optional See basic usage for more information. package-mode = false name The name of the package. Required in package mode This should be a valid name as defined by PEP 508. name = "my-package" version The version of the package. Required in package mode This should be a valid PEP 440 string.

Repositories Poetry supports the use of PyPI and private repositories for discovery of packages as well as for publishing your projects. By default, Poetry is configured to use the PyPI repository, for package installation and publishing. So, when you add dependencies to your project, Poetry will assume they are available on PyPI. This represents most cases and will likely be enough for most users. Private Repository Example Installing from private package sources By default, Poetry discovers and installs packages from PyPI. But, you want to install a dependency to your project for a simple API repository? Let’s do it.

Managing dependencies Poetry supports specifying main dependencies in the project.dependencies section of your pyproject.toml according to PEP 621. For legacy reasons and to define additional information that are only used by Poetry the tool.poetry.dependencies sections can be used. See Dependency specification for more information. Dependency groups Poetry provides a way to organize your dependencies by groups. The dependencies declared in project.dependencies respectively tool.poetry.dependencies are part of an implicit main group. Those dependencies are required by your project during runtime.

Managing environments Poetry makes project environment isolation one of its core features. What this means is that it will always work isolated from your global Python installation. To achieve this, it will first check if it’s currently running inside a virtual environment. If it is, it will use it directly without creating a new one. But if it’s not, it will use one that it has already created or create a brand new one for you.

Basic usage For the basic usage introduction we will be installing pendulum, a datetime library. If you have not yet installed Poetry, refer to the Introduction chapter. Project setup First, let’s create our new project, let’s call it poetry-demo: poetry new poetry-demo This will create the poetry-demo directory with the following content: poetry-demo ├── pyproject.toml ├── README.md ├── poetry_demo │ └── __init__.py └── tests └── __init__.py The pyproject.toml file is what is the most important here. This will orchestrate your project and its dependencies. For now, it looks like this:
