Pyright

Pyright is a static type checker for Python that analyzes code without executing it to detect type errors, inconsistencies, and potential bugs. It is designed to be fast, configurable, and supports modern Python features like type hints, async/await, and dataclasses. Pyright is commonly integrated into code editors and IDEs to provide real-time feedback during development.

Also known as: PyRight, Py right, Microsoft Pyright, Pyright type checker, Pylance (when integrated with VS Code)

Why learn Pyright?

Developers should use Pyright when working on large Python codebases or projects that require high reliability, as it helps catch type-related errors early in the development cycle. It is particularly valuable for teams adopting type hints to improve code readability and maintainability, and for integrating with CI/CD pipelines to enforce type safety automatically.
