## Type Hints with Metadata Annotations { #type-hints-with-metadata-annotations }

Python also has a feature that allows putting **additional <abbr title="Data about the data, in this case, information about the type, e.g. a description.">metadata</abbr>** in these type hints using `Annotated`.

//// tab | Python 3.9+

In Python 3.9, `Annotated` is part of the standard library, so you can import it from `typing`.
