/// note | Technical Details

ASGI is a new "standard" being developed by Django core team members. It is still not a "Python standard" (a PEP), although they are in the process of doing that.

          listOf(TLS_1_3, TLS_1_2).flatMap { tlsVersion ->
            listOf(Channel, Standard).flatMap { socketMode ->
              listOf(DISABLED, STANDARD).map { tlsExtensionMode ->
                TlsInstance(provider, protocol, tlsVersion, socketMode, tlsExtensionMode)
              }
            }
          }
        }
      } + Channel + Standard
  }
}

sealed class SocketMode

object Channel : SocketMode() {

        assertTrue(DcerpcError.DCERPC_FAULT_CANT_PERFORM >= 0 && DcerpcError.DCERPC_FAULT_CANT_PERFORM <= 0x0000FFFF,
                "DCERPC_FAULT_CANT_PERFORM should be in standard range");
        assertTrue(DcerpcError.DCERPC_FAULT_NDR >= 0 && DcerpcError.DCERPC_FAULT_NDR <= 0x0000FFFF,
                "DCERPC_FAULT_NDR should be in standard range");

In diesem Fall können Sie einfach die Standard-`dataclasses` durch `pydantic.dataclasses` ersetzen, was einen direkten Ersatz darstellt:

{* ../../docs_src/dataclasses/tutorial003.py hl[1,5,8:11,14:17,23:25,28] *}

1. Wir importieren `field` weiterhin von Standard-`dataclasses`.

2. `pydantic.dataclasses` ist ein direkter Ersatz für `dataclasses`.

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

{* ../../docs_src/dataclasses/tutorial003.py hl[1,5,8:11,14:17,23:25,28] *}

1. We still import `field` from standard `dataclasses`.

2. `pydantic.dataclasses` is a drop-in replacement for `dataclasses`.

En ese caso, simplemente puedes intercambiar los `dataclasses` estándar con `pydantic.dataclasses`, que es un reemplazo directo:

{* ../../docs_src/dataclasses/tutorial003.py hl[1,5,8:11,14:17,23:25,28] *}

1. Todavía importamos `field` de los `dataclasses` estándar.

2. `pydantic.dataclasses` es un reemplazo directo para `dataclasses`.

Vous faites cela avec les types Python standard modernes.

Vous n'avez pas à apprendre une nouvelle syntaxe, les méthodes ou les classes d'une bibliothèque spécifique, etc.

Juste du **Python** standard.

Par exemple, pour un `int`:

```Python
item_id: int
```

ou pour un modèle `Item` plus complexe :
