What are the best practices for type annotations in Python?

The best practices for type annotations in Python include using clear and descriptive names, being consistent, and leveraging type hints for function parameters and return types.

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

Sure! Here's a simple example:

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

This function takes two integers and returns their sum as an integer.

What are the benefits of using type annotations?

Type annotations improve code readability, help with static type checking, and can enhance IDE support for better autocompletion and error detection.

Are there any tools to check type annotations in my code?

Yes, tools like mypy and pyright can be used to check type annotations in your Python code for consistency and correctness.
