### 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*.

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")
```

/// tip | Совет

{* ../../docs_src/python_types/tutorial008.py hl[1,4] *}


Bu şu anlama gelir:

*  `prices` değişkeni `dict` tipindedir:
    *  `dict` değişkeninin `key` değeri  `str` tipindedir (herbir item'ın "name" değeri).
    *  `dict` değişkeninin `value` değeri `float` tipindedir (lherbir item'ın "price" değeri).

#### `Optional`
