#### `Union` oder `Optional` verwenden? { #using-union-or-optional }

Wenn Sie eine Python-Version unterhalb 3.10 verwenden, hier ist mein sehr **subjektiver** Standpunkt dazu:

* 🚨 Vermeiden Sie `Optional[SomeType]`
* Stattdessen ✨ **verwenden Sie `Union[SomeType, None]`** ✨.

     * The default value is empty.

    default Optional<String> module() {

     * {@return the version of the platform where the code will be executed}
     * In a Java environment, this is the value of the {@code --release} compiler option.
     * The default value is empty.
     */
    default Optional<Version> targetVersion() {
        return Optional.empty();

        com.google.common.base.Optional.of("2"),

#### Использовать `Union` или `Optional` { #using-union-or-optional }

Если вы используете версию Python ниже 3.10, вот совет с моей весьма **субъективной** точки зрения:

* 🚨 Избегайте использования `Optional[SomeType]`
* Вместо этого ✨ **используйте `Union[SomeType, None]`** ✨.
