## Add more validations

You can also add a parameter `min_length`:

=== "Python 3.10+"

    ```Python hl_lines="10"
    {!> ../../../docs_src/query_params_str_validations/tutorial003_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="10"
    {!> ../../../docs_src/query_params_str_validations/tutorial003_an_py39.py!}
    ```

=== "Python 3.8+"

```Python hl_lines="10"
{!../../../docs_src/query_params_str_validations/tutorial004.py!}
```

Cette expression régulière vérifie que la valeur passée comme paramètre :
