This blog post provides a tutorial on setting up the type checker 'ty' for a Python project using 'uv'. It includes practical examples by introducing three bugs that a test suite would overlook and discusses how to fine-tune the rules enforced by 'ty'. The post also compares 'ty' to 'Pyrefly' as a type checker option and outlines the prerequisites needed for setup, emphasizing the benefits of using 'ty' for its integrated toolchain across linting, packaging, and type checking.
