Linters are tools that analyze a program’s source code to detect various
problems such as syntax errors, programming mistakes, style violations, and
more. They are important for maintaining code quality and
readability in a project, as well as for catching bugs early in the
development cycle. Last year, a new Python linter appeared: Ruff. It’s fast, written in Rust, and in less than a year it has
been adopted by some high-profile projects, including FastAPI, Pandas, and SciPy.
