### Usar el nombre de la *path operation function* como el operationId { #using-the-path-operation-function-name-as-the-operationid }

Si quieres usar los nombres de las funciones de tus APIs como `operationId`s, puedes iterar sobre todas ellas y sobrescribir el `operation_id` de cada *path operation* usando su `APIRoute.name`.

Deberías hacerlo después de agregar todas tus *path operations*.

### Utilizando o nome da *função de operação de rota* como o operationId { #using-the-path-operation-function-name-as-the-operationid }

Se você quiser utilizar o nome das funções da sua API como `operationId`s, você pode iterar sobre todos esses nomes e sobrescrever o `operation_id` em  cada *operação de rota* utilizando o `APIRoute.name` dela.

Você deve fazer isso depois de adicionar todas as suas *operações de rota*.

Например, у вас есть файл `main.py`:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

    *  `dict` değişkeninin `value` değeri `float` tipindedir (lherbir item'ın "price" değeri).
