What are advanced annotations in Python 3?

Advanced annotations in Python 3 refer to the use of type hints and annotations to provide more information about function parameters and return types.

Can you give me an example of how to use them?

Sure! Here's a simple example:

from typing import List, Dict

def process_data(data: List[Dict[str, int]]) -> None:
    pass

This function takes a list of dictionaries with string keys and integer values.

What are the benefits of using these annotations?

Using annotations improves code readability, helps with static type checking, and enhances IDE support for better autocompletion.

Are there any limitations to using annotations?

Yes, annotations are not enforced at runtime, so they serve as hints rather than strict type checks. It's important to use them wisely.
