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).
