Using Poetry

Poetry - Python dependency management and packaging made easy

Poetry is a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

Initialize a new project

This command starts an interactive process to create a new pyproject.toml file. It guides you through defining your project's metadata, including name, version, description, author, license, and dependencies.

poetry init

Install project dependencies

This command reads the pyproject.toml file in your project, resolves the dependencies, and installs them into a new virtual environment.

If a poetry.lock file exists, it uses this to ensure reproducible installations across different environments.

poetry install

Enter the virtual environment

This command spawns a new shell with the virtual environment activated. It allows you to run your project and its dependencies in an isolated environment, ensuring that you're using the correct versions of all packages.

poetry shell

Deactivate the virtual environment

To exit the Poetry shell and deactivate the virtual environment, you can use:

exit
