For example, let's define a variable to be a `list` of `str`.

=== "Python 3.9+"

    Declare the variable, with the same colon (`:`) syntax.

    As the type, put `list`.

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

    ```Python hl_lines="1"
    {!> ../../../docs_src/python_types/tutorial006_py39.py!}
    ```

=== "Python 3.8+"

```Python
{!../../../docs_src/python_types/tutorial001.py!}
```

### ✍ ⚫️

⚫️ 📶 🙅 📋.

Trong Python 3.6 hoặc lớn hơn (bao gồm Python 3.10) bạn có thể sử dụng kiểu `Union` từ `typing` và đặt trong dấu ngoặc vuông những giá trị được chấp nhận.

In Python 3.10 there's also a **new syntax** where you can put the possible types separated by a <abbr title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</abbr>.

Était-ce `upper` ? `uppercase` ? `first_uppercase` ? `capitalize` ?

Vous essayez donc d'utiliser le vieil ami du programmeur, l'auto-complétion de l'éditeur.

Vous écrivez le premier paramètre, `first_name`, puis un point (`.`) et appuyez sur `Ctrl+Espace` pour déclencher l'auto-complétion.

Mais malheureusement, rien d'utile n'en résulte :
