## Upload de Arquivo Opcional { #optional-file-upload }

Você pode tornar um arquivo opcional usando anotações de tipo padrão e definindo um valor padrão de `None`:

{* ../../docs_src/request_files/tutorial001_02_an_py310.py hl[9,17] *}

			// then it is implicit on for the sub-system.
			enabled = true

		v, _ := currKVS.Lookup(hkv.Key)
		if v == "" && !hkv.Optional && enabled {
			// Return error only if the
			// key is enabled, for state=off
			// let it be empty.
			return false, Errorf(
				"'%s' is not optional for '%s' sub-system, please check '%s' documentation",
				hkv.Key, subSys, subSys)

# Einführung in Python-Typen { #python-types-intro }

Python hat Unterstützung für optionale „Typhinweise“ (auch „Typannotationen“ genannt).

Diese **„Typhinweise“** oder -Annotationen sind eine spezielle Syntax, die es erlaubt, den <dfn title="zum Beispiel: str, int, float, bool">Typ</dfn> einer Variablen zu deklarieren.

Durch das Deklarieren von Typen für Ihre Variablen können Editoren und Tools bessere Unterstützung bieten.

	// The LRU Key of this element.
	Key K

	// The Value stored with this element.
	Value V

	// The time this element would be cleaned up, optional
	ExpiresAt time.Time

	// The expiry bucket item was put in, optional
	ExpireBucket uint8
}

// PrevEntry returns the previous list element or nil.
