How can I create custom types using the Python typing module?

You can create custom types in Python using the typing module by defining classes and using type hints.

Can you show me an example of a custom type?

Sure! Here's a simple example:

from typing import NewType

UserId = NewType('UserId', int)

This creates a new type UserId that is based on int.

What are the benefits of using custom types?

Custom types improve code readability and help with type checking, making your code more robust.

Are there any limitations to using the typing module?

Yes, while the typing module is powerful, it doesn't enforce type checks at runtime, so it's mainly for static analysis.
