As the type, put the `List` that you imported from `typing`.

As the list is a type that contains some internal types, you put them in square brackets:

```Python hl_lines="4"
{!> ../../docs_src/python_types/tutorial006.py!}
```

////

/// info

Those internal types in the square brackets are called "type parameters".

In this case, `str` is the type parameter passed to `List` (or `list` in Python 3.9 and above).

server allows WORM for specific objects or by configuring a bucket with default object lock configuration that applies default retention mode and retention duration to all objects. This makes objects in the bucket immutable i.e. delete of the version are not allowed until an expiry specified in the bucket's object lock configuration or object retention.

Object locking requires locking to be enabled on a bucket at the time of bucket creation refer to `mc mb --with-lock`, object locking enables...
