Pyright
A Python static type checker developed by Microsoft that serves as the underlying engine for the Pylance VS Code extension. It is noted for high performance and strict type inference.
Timeline (last 90 days)
Pyrefly aims to provide type checking an order of magnitude faster than mypy and Pyright, and to support full type inference, generics, and the new PEP 695 syntax.
Pyrefly's type checking rules are not entirely consistent with Pyright's, so migrating a project may require handling newly appearing diagnostics.
Zed's previously built-in Python options relied mainly on pyright or on basedpyright, ruff and others configured by users themselves.
使用 Mapped[] 语法时，框架可在无需额外元数据的情况下推断列类型、是否可空以及关系的加载方式，使 mypy、Pyright 等静态分析工具能够理解 ORM 对象的属性类型
