Python type hints provide optional type annotations that help developers write cleaner, more maintainable code without affecting runtime behavior. The feature allows static analysis tools and IDEs to catch type-related errors before code execution. Key concepts include basic variable and function annotations, container type hints for lists and dictionaries, Union and Optional types for flexible typing, class-based type hints, and deferred evaluation for forward references. Type hints are purely for development-time assistance and don't impact Python's dynamic nature at runtime.
