What are Python typing tools and how can they help my code?

Python typing tools help you add type hints to your code, improving readability and reducing bugs.

Can you give me an example of how to use type hints in a function?

Sure! Here's a simple example:

def add_numbers(a: int, b: int) -> int: return a + b

This specifies that both 'a' and 'b' should be integers and the function returns an integer.

What tools can I use to check type hints in my code?

You can use tools like mypy, Pyright, or Pyre to check type hints and ensure type safety in your code.

Are there any downsides to using type hints?

While type hints improve code quality, they can add some overhead in terms of learning and may require additional tooling.
