### Editor Unterstützung

         * Returns the option followed by a string representation of the given path elements.
         * The path elements are separated by an option-specific or platform-specific separator.
         * If the given {@code paths} argument contains no element, then this method returns an empty string.
         *
         * @param paths the path to format as a string
         * @return the option associated to this path type followed by the given path elements,

     * then set the result of the computation, and only then transition to COMPLETED, CANCELLED, or
     * INTERRUPTED.
     *
     * <p>We don't use the integer argument passed between acquire methods so we pass around a -1
     * everywhere.

### Python 3.10에서 `Union`

위의 예제에서는 `response_model` 인자 값으로 `Union[PlaneItem, CarItem]`을 전달합니다.

이 경우, 이를 **타입 어노테이션(type annotation)** 이 아닌 **인자 값(argument value)** 으로 전달하고 있기 때문에 Python 3.10에서도 `Union`을 사용해야 합니다.

만약 타입 어노테이션에 사용한다면, 다음과 같이 수직 막대(|)를 사용할 수 있습니다:

```Python
some_variable: PlaneItem | CarItem
```

# Symlink a directory, to have it pretend be the T:\ drive.
# This drive letter is used by internal CI,
# and part of it is mounted to the container during the container's creation.
#
# While the mount argument (`-v host_path:container_path`) still requires
# `container_path` to be a legitimate C:\ path, in this case, 'C:\drive_t',
# this symlink does allow for the convenience of passing unedited paths

`**second_user_data` quer dizer:

Passe as chaves e valores do dicionário `second_user_data` diretamente como argumentos chave-valor, equivalente a: `User(id=4, name="Mary", joined="2018-11-30")`

#### Sobre `**user_dict`

`UserInDB(**user_dict)` significa:

*Passe as keys (chaves) e values (valores) de `user_dict` diretamente como argumentos de valor-chave, equivalente a:*

```Python
UserInDB(
    username = user_dict["username"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    disabled = user_dict["disabled"],

auch beschweren.

Wenn Sie aber nicht `Annotated` benutzen und stattdessen die **(alte) Variante mit einem Defaultwert**, dann müssen Sie, wenn Sie die Funktion ohne FastAPI an **anderen Stellen** aufrufen, sich daran **erinnern**, die Argumente der Funktion zu übergeben, damit es richtig funktioniert. Ansonsten erhalten Sie unerwartete Werte (z. B. `QueryInfo` oder etwas Ähnliches, statt `str`). Ihr Editor kann ihnen nicht helfen, und Python wird die Funktion ohne Beschwerden ausführen,...

### `FileResponse`

Transmite un archivo asincrónicamente como response.

Toma un conjunto diferente de argumentos para crear un instance que los otros tipos de response:

* `path` - La path del archivo para el archivo a transmitir.
* `headers` - Cualquier header personalizado para incluir, como un diccionario.
