Hints in Python, also known as type hints, allow you to specify the expected type of variables, function parameters, and return values. They improve code readability and help with debugging. For instance, a function that adds two integers can be annotated as `def add(x: int, y: int) -> int:`. These hints are optional and don't enforce type checking at runtime but are useful for development tools and IDEs.
