1What is Ruff in the Python ecosystem?
What is Ruff in the Python ecosystem?
Answer
Ruff is an extremely fast Python linter and formatter written in Rust. It advantageously replaces tools like Flake8, isort, and Black while offering 10 to 100 times better performance. Ruff supports over 700 linting rules and easily integrates into CI/CD pipelines and pre-commit hooks.
2What is the main role of the pyproject.toml file with Poetry?
What is the main role of the pyproject.toml file with Poetry?
Answer
The pyproject.toml file is the central configuration file for a Python project with Poetry. It defines project metadata (name, version, description), production and development dependencies, scripts, and tool configurations like Ruff or pytest. This standardized file replaces setup.py, requirements.txt, and setup.cfg.
3Which Poetry command installs all dependencies of an existing project?
Which Poetry command installs all dependencies of an existing project?
Answer
The poetry install command reads pyproject.toml and poetry.lock files to install all project dependencies in an isolated virtual environment. If poetry.lock exists, exact versions are used to ensure reproducibility. Otherwise, Poetry resolves dependencies and creates the lock file.
What is a pre-commit hook in the Git context?
What is the basic structure of a GitHub Actions workflow?
