What are some examples of using the Python typing module?

Can you give me some examples of how to use the Python typing module?

Sure! The Python typing module provides support for type hints. For example, you can use List and Dict to specify types for lists and dictionaries.

Can you show me a specific example with a function?

Absolutely! Here's a simple function that takes a list of integers and returns their sum:

from typing import List

def sum_numbers(numbers: List[int]) -> int:
    return sum(numbers)

What about using typing for a dictionary?

You can use Dict to specify key-value pairs. For example:

from typing import Dict

def get_value(data: Dict[str, int], key: str) -> int:
    return data.get(key, 0)

Are there any other useful types in the typing module?

Yes! There are several, like Tuple, Union, and Optional, which can help you define more complex types.
