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!}
```

!!! check "**FastAPI** uses it to"
    Handle all the data validation, data serialization and automatic model documentation (based on JSON Schema).

    **FastAPI** then takes that JSON Schema data and puts it in OpenAPI, apart from all the other things it does.

Az önceki örneğe geri dönelim, **FastAPI**'ın yapacaklarına bir bakış atalım:

* `item_id`'nin `GET` ve `PUT` istekleri için, yolda olup olmadığının kontol edecek.
* `item_id`'nin `GET` ve `PUT` istekleri için, tipinin `int` olduğunu doğrulayacak.
    * Eğer değilse, sebebini belirten bir hata mesajı gösterecek.
