Python Type Safety

Implement comprehensive type safety in Python 3.10+ projects using static type checking with mypy and runtime validation with Pydantic.

When to Use This Skill

• Adding type hints to existing Python code
• Creating new typed modules and packages
• Configuring mypy for strict type checking
• Implementing Pydantic models for data validation
• Migrating from untyped to fully typed code
• Reviewing type coverage in a codebase
