Type Hints and Documentation

Concepts: pyTypeHints

As programs grow larger and teams work together, it becomes important to document what types of values functions expect and return. Python provides type hints, which are annotations that describe expected types. Type hints do not change how code runs; they are documentation for humans and tools. Basic Type Hints Type Hints Are Not Enforced Why Use Type Hints? Type hints provide significant benefits for code quality and maintainability, especially in larger codebases and team environments. Adopting type hints early builds a habit that pays off as your codebase grows. The broader Python ecosystem has invested heavily in type hinting infrastructure. Common Mistakes Everyone makes these mistakes when learning functions. Knowing about them helps you recognize and fix them quickly when they happ
