Использование `str | None` вместо просто `str` позволит редактору кода помочь вам обнаружить ошибки, когда вы предполагаете, что значение всегда `str`, хотя на самом деле оно может быть и `None`.

### Классы как типы { #classes-as-types }

Вы также можете объявлять класс как тип переменной.

Допустим, у вас есть класс `Person` с именем:

{* ../../docs_src/python_types/tutorial010_py310.py hl[1:3] *}

		return
	case o.Prefix == o.BaseDir:
		// No additional prefix
		return
	}
	// Remove basedir.
	o.FilterPrefix = strings.TrimPrefix(o.Prefix, o.BaseDir)
	// Remove leading and trailing slashes.
	o.FilterPrefix = strings.Trim(o.FilterPrefix, slashSeparator)

	if strings.Contains(o.FilterPrefix, slashSeparator) {
		// Sanity check, should not happen.
		o.FilterPrefix = ""
	}
}

/**
 * Static methods pertaining to ASCII characters (those in the range of values {@code 0x00} through

 * <ul>

 *   <li>{@link StandardCharsets#US_ASCII} specifies the {@code Charset} of ASCII characters.

Nous pouvons faire mieux.

Nous pouvons déclarer un modèle `UserBase` qui sert de base à nos autres modèles. Ensuite, nous pouvons créer des sous-classes de ce modèle qui héritent de ses attributs (déclarations de type, validation, etc.).

Toutes les conversions de données, validations, documentation, etc., fonctionneront comme d'habitude.
