        Prefer to use the `Annotated` version if possible.

Но если вы хотите сделать query-параметр обязательным, вы можете просто не указывать значение по умолчанию:

```Python hl_lines="6-7"
{!../../../docs_src/query_params/tutorial005.py!}
```

Здесь параметр запроса `needy` является обязательным параметром с типом данных  `str`.

Если вы откроете в браузере URL-адрес, например:

```

Pero cuando quieres hacer que un parámetro de query sea requerido, puedes simplemente no declararle un valor por defecto:

```Python hl_lines="6-7"
{!../../../docs_src/query_params/tutorial005.py!}
```

Aquí el parámetro de query `needy` es un parámetro de query requerido, del tipo `str`.

Si abres tu navegador en una URL como:

```

Porém, quando você quiser fazer com que o parâmetro de consulta seja obrigatório, você pode simplesmente não declarar nenhum valor como padrão.

```Python hl_lines="6-7"
{!../../../docs_src/query_params/tutorial005.py!}
```

Aqui o parâmetro de consulta `needy` é um valor obrigatório, do tipo `str`.

Se você abrir no seu navegador a URL:
