python-type-safety

Static type checking in Python works by using mypy or pyright to analyze type annotations, generics, and protocols without executing code, catching type errors early. This mechanism embeds type information directly into your codebase and CI workflows to enforce safety.

Configure strict type checking in CI pipelines by integrating mypy or pyright into your workflow to analyze type annotations and enforce type safety automatically. This setup ensures every commit is validated against strict typing rules, preventing type errors from merging.

Yes, this approach supports modern Python typing features including generics, protocols, type narrowing, and modern union syntax. These features allow you to build robust, type-safe APIs and design generic structures that enforce strict type safety across your codebase.

The best way to add type annotations is to start with public APIs, apply type hints progressively, and run static type checkers like mypy or pyright to reveal type errors. This gradual approach enforces type safety without requiring a complete codebase rewrite.

You need type narrowing and modern union syntax when designing generic structures and robust APIs that require strict type safety. These typing features allow static analysis tools like mypy and pyright to accurately track and enforce type changes within your code logic.
