```

... rend le paramètre optionnel, et est donc équivalent à :

```Python
q: Union[str, None] = None
```

Mais déclare explicitement `q` comme étant un paramètre de requête.

!!! info
    Gardez à l'esprit que la partie la plus importante pour rendre un paramètre optionnel est :

    ```Python
    = None
    ```

    ou :

    ```Python
    = Query(None)
    ```

Se você precisa refrescar a memória rapidamente sobre como usar tipos do Python (mesmo que você não use o FastAPI), confira esse rápido tutorial: [Tipos do Python](python-types.md){.internal-link target=_blank}.

Você escreve Python padrão com tipos:

```Python
from datetime import date

from pydantic import BaseModel

# Declare uma variável como str
# e obtenha suporte do editor dentro da função
def main(user_id: str):

		isubdom := globalBrowserConfig.IsHSTSIncludeSubdomains()
		isprel := globalBrowserConfig.IsHSTSPreload()
		os.Setenv("CONSOLE_SECURE_STS_SECONDS", strconv.Itoa(hstsSeconds))
		os.Setenv("CONSOLE_SECURE_STS_INCLUDE_SUB_DOMAINS", isubdom)
		os.Setenv("CONSOLE_SECURE_STS_PRELOAD", isprel)
	}

	if valueRefer := globalBrowserConfig.GetReferPolicy(); valueRefer != "" {

The links and the invocations' status can then be printed out, or output in the
form of JUnit-based XML.
