Он существует специально для поддержки подсказок этих типов.

#### `List`

Например, давайте определим переменную как `list`, состоящий из `str`.

Импортируйте `List` из `typing` (с заглавной `L`):

{* ../../docs_src/python_types/tutorial006.py hl[1] *}


Объявите переменную с тем же синтаксисом двоеточия (`:`).

В качестве типа укажите `List`.

    return new WrappedCollection(key, collection, null);
  }

  final List<V> wrapList(
      @ParametricNullness K key, List<V> list, @Nullable WrappedCollection ancestor) {
    return (list instanceof RandomAccess)
        ? new RandomAccessWrappedList(key, list, ancestor)
        : new WrappedList(key, list, ancestor);
  }

When you create a **FastAPI** *path operation* you can normally return any data from it: a `dict`, a `list`, a Pydantic model, a database model, etc.

By default, **FastAPI** would automatically convert that return value to JSON using the `jsonable_encoder` explained in [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.
