Pour déclarer ces types et les types internes, on utilise le module standard de Python `typing`.

Il existe spécialement pour supporter ces annotations de types.

#### `List`

Par exemple, définissons une variable comme `list` de `str`.

Importez `List` (avec un `L` majuscule) depuis `typing`.

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

## Пример { #example }

### Создание { #create-it }

Создайте файл `main.py` со следующим содержимым:

```Python
