It is designed for high performance and can be used with large Python source bases.\n\nPyright includes both a [command-line tool](https://microsoft.github.io/pyright/#/command-line) and an [extension for Visual Studio Code](https://marketplace.visualstudio.com/items?itemName=ms-pyright.pyright).\n\n\n## Pyright Playground\n\nTry Pyright in your browser using the [Pyright Playground](https://pyright-play.net/?code=MQAgKgFglgziMEMC2AHANgUxAEw0g9gHYwAuATgiRnBPgO4gDG%2BSBhIGZZ%2BZcjC7AEZZcVRlWzwSlKPzRoAniEFKUCslADmEEgDoAUPtwAzEAmzYAFAA8AXCGNp8lADQgF9x85IBKW-pBAkDIMEgBXMnZrEABqd0NQAAUEGBgoQk0zKTIQdNIBRiwUkBIILBgMZkJJBDJNMKQMQhJg6jC0Ejh0rLIw5qhGjmtClBIoIgNzKwBGNwAiOZ99IA).\n\n\n## Documentation\n\nRefer to [the documentation](https://microsoft.github.io/pyright) for installation, configuration, and usage details.\n\n\n## Environment variables\n\nIf Pyright fails to create a temporary directory (for example in remote/server environments where the OS temp directory doesn\u0027t exist or isn\u0027t writable), you can override the temp directory root:\n\n- `PYRIGHT_TMPDIR`: Absolute path to a directory that Pyright can use for temporary files/directories. Pyright will create it if needed.\n\nPyright otherwise relies on the platform temp directory (for example `TMPDIR`, `TMP`, `TEMP`, or the OS default).\n\n\n## Community\nDo you have questions about Pyright or Python type annotations in general? Post your questions in [the discussion section](https://github.com/microsoft/pyright/discussions).\n\nIf you would like to report a bug or request an enhancement, file a new issue in either the [pyright](https://github.com/microsoft/pyright/issues) or [pylance-release](https://github.com/microsoft/pylance-release/issues) issue tracker.

It\u0027s significantly faster than mypy on large codebases and integrates tightly with VS Code. Use it in CI/CD pipelines or pre-commit hooks to maintain type safety across your Python project."
