poetry.lock

poetry.lock is a file generated by the Poetry dependency manager for Python projects. Poetry is a tool that simplifies Python package management and project dependency resolution. When you use Poetry to manage your project’s dependencies, it creates a pyproject.toml file to specify project metadata and dependencies, and a poetry.lock file to lock down the exact versions of the dependencies.

By including the poetry.lock file in your version control system, e.g. Git, you ensure that all collaborators or deployment environments use the exact same versions of dependencies, minimizing potential compatibility issues and creating a reproducible environment.
