An example of an AI chatbot conversation about Python 3.10 type hints and related tools.
What are the new type hinting features in Python 3.10?
Python 3.10 introduced several enhancements to type hinting, including the new syntax for union types using the pipe operator (|) and the ability to use 'TypeGuard' for more precise type narrowing.
Can you explain how to use the new union type syntax?
Sure! Instead of using 'Union[int, str]', you can now simply write 'int | str' to indicate that a variable can be either an integer or a string.
What tools can help with type hinting in Python?
Some popular tools include mypy for static type checking, Pyright for fast type checking, and Pylance for enhanced IntelliSense in VS Code.
Are there any best practices for using type hints?
Yes! It's best to use type hints consistently, avoid over-complicating them, and leverage them to improve code readability and maintainability.
