An example of an AI chatbot conversation about best practices for type annotations in Python 3.10.
What are the best practices for type annotations in Python 3.10?
In Python 3.10, best practices for type annotations include using the new syntax for union types, leveraging type aliases, and keeping annotations clear and concise.
Can you explain the new syntax for union types?
Sure! Instead of using 'Union[X, Y]', you can now use 'X | Y' to denote a union of types, which is more readable.
What are type aliases and how do I use them?
Type aliases allow you to create a new name for an existing type. For example, you can define 'Vector = List[float]' to simplify type hints.
Are there any tools to help with type checking?
Yes, tools like mypy and Pyright can help you perform static type checking in your Python code, ensuring type safety.
