Python 3.9+ + +Declareer de variabele met dezelfde dubbele punt (`:`) syntax. + +Als type, vul `list` in. + +Doordat de list een type is dat enkele interne types bevat, zet je ze tussen vierkante haakjes: + +```Python hl_lines="1" +{!> ../../../docs_src/python_types/tutorial006_py39.py!} +``` + +//// + +//// tab | Python 3.8+ + +Van `typing`, importeer `List` (met een hoofdletter `L`): + +```Python hl_lines="1" +{!> ../../../docs_src/python_types/tutorial006.py!} +``` + +Declareer de variabele met dezelfde dubbele punt (`:`) syntax. + +Zet als type de `List` die je hebt geïmporteerd uit `typing`. + +Doordat de list een type is dat enkele interne types bevat, zet je ze tussen vierkante haakjes: + +```Python hl_lines="4" +{!> ../../../docs_src/python_types/tutorial006.py!} +``` + +//// + +/// info + +De interne types tussen vierkante haakjes worden “typeparameters” genoemd. + +In dit geval is `str` de typeparameter die wordt doorgegeven aan `List` (of `list` in Python 3.9 en hoger). + +/// + +Dat betekent: “de variabele `items` is een `list`, en elk van de items in deze list is een `str`”. + +/// tip + +Als je Python 3.9 of hoger gebruikt, hoef je `List` niet te importeren uit `typing`, je kunt in plaats daarvan hetzelfde reguliere `list` type gebruiken. + +/// + +Door dat te doen, kan je editor ondersteuning bieden, zelfs tijdens het verwerken van items uit de list: + + + +Zonder types is dat bijna onmogelijk om te bereiken. + +Merk op dat de variabele `item` een van de elementen is in de lijst `items`. + +Toch weet de editor dat het een `str` is, en biedt daar vervolgens ondersteuning voor aan. + +#### Tuple en Set + +Je kunt hetzelfde doen om `tuple`s en `set`s te declareren: + +//// tab | Python 3.9+ + +```Python hl_lines="1" +{!> ../../../docs_src/python_types/tutorial007_py39.py!} +``` + +//// + +//// tab | Python 3.8+ + +```Python hl_lines="1 4" +{!> ../../../docs_src/python_types/tutorial007.py!} +``` + +//// + +Dit betekent: + +* De variabele `items_t` is een `tuple` met 3 items, een `int`, nog een `int`, en een `str`. +* De variabele `items_s` is een `set`, en elk van de items is van het type `bytes`. + +#### Dict + +Om een `dict` te definiëren, geef je 2 typeparameters door, gescheiden door komma's. + +De eerste typeparameter is voor de sleutels (keys) van de `dict`. + +De tweede typeparameter is voor de waarden (values) van het `dict`: + +//// tab | Python 3.9+ + +```Python hl_lines="1" +{!> ../../../docs_src/python_types/tutorial008_py39.py!} +``` + +//// + +//// tab | Python 3.8+ + +```Python hl_lines="1 4" +{!> ../../../docs_src/python_types/tutorial008.py!} +``` + +//// + +Dit betekent: + +* De variabele `prices` is een `dict`: + * De sleutels van dit `dict` zijn van het type `str` (bijvoorbeeld de naam van elk item). + * De waarden van dit `dict` zijn van het type `float` (bijvoorbeeld de prijs van elk item). + +#### Union + +Je kunt een variable declareren die van **verschillende types** kan zijn, bijvoorbeeld een `int` of een `str`. + +In Python 3.6 en hoger (inclusief Python 3.10) kun je het `Union`-type van `typing` gebruiken en de mogelijke types die je wilt accepteren, tussen de vierkante haakjes zetten. + +In Python 3.10 is er ook een **nieuwe syntax** waarin je de mogelijke types kunt scheiden door een verticale balk (`|`). + +//// tab | Python 3.10+ + +```Python hl_lines="1" +{!> ../../../docs_src/python_types/tutorial008b_py310.py!} +``` + +//// + +//// tab | Python 3.8+ + +```Python hl_lines="1 4" +{!> ../../../docs_src/python_types/tutorial008b.py!} +``` + +//// + +In beide gevallen betekent dit dat `item` een `int` of een `str` kan zijn. + +#### Mogelijk `None` + +Je kunt declareren dat een waarde een type kan hebben, zoals `str`, maar dat het ook `None` kan zijn. + +In Python 3.6 en hoger (inclusief Python 3.10) kun je het declareren door `Optional` te importeren en te gebruiken vanuit de `typing`-module. + +```Python hl_lines="1 4" +{!../../../docs_src/python_types/tutorial009.py!} +``` + +Door `Optional[str]` te gebruiken in plaats van alleen `str`, kan de editor je helpen fouten te detecteren waarbij je ervan uit zou kunnen gaan dat een waarde altijd een `str` is, terwijl het in werkelijkheid ook `None` zou kunnen zijn. + +`Optional[EenType]` is eigenlijk een snelkoppeling voor `Union[EenType, None]`, ze zijn equivalent. + +Dit betekent ook dat je in Python 3.10 `EenType | None` kunt gebruiken: + +//// tab | Python 3.10+ + +```Python hl_lines="1" +{!> ../../../docs_src/python_types/tutorial009_py310.py!} +``` + +//// + +//// tab | Python 3.8+ + +```Python hl_lines="1 4" +{!> ../../../docs_src/python_types/tutorial009.py!} +``` + +//// + +//// tab | Python 3.8+ alternative + +```Python hl_lines="1 4" +{!> ../../../docs_src/python_types/tutorial009b.py!} +``` + +//// + +#### Gebruik van `Union` of `Optional` + +Als je een Python versie lager dan 3.10 gebruikt, is dit een tip vanuit mijn **subjectieve** standpunt: + +* 🚨 Vermijd het gebruik van `Optional[EenType]`. +* Gebruik in plaats daarvan **`Union[EenType, None]`** ✨. + +Beide zijn gelijkwaardig en onderliggend zijn ze hetzelfde, maar ik zou `Union` aanraden in plaats van `Optional` omdat het woord “**optional**” lijkt te impliceren dat de waarde optioneel is, en het eigenlijk betekent “het kan `None` zijn”, zelfs als het niet optioneel is en nog steeds vereist is. + +Ik denk dat `Union[SomeType, None]` explicieter is over wat het betekent. + +Het gaat alleen om de woorden en naamgeving. Maar die naamgeving kan invloed hebben op hoe jij en je teamgenoten over de code denken. + +Laten we als voorbeeld deze functie nemen: + +```Python hl_lines="1 4" +{!../../../docs_src/python_types/tutorial009c.py!} +``` + +De parameter `name` is gedefinieerd als `Optional[str]`, maar is **niet optioneel**, je kunt de functie niet aanroepen zonder de parameter: + +```Python +say_hi() # Oh, nee, dit geeft een foutmelding! 😱 +``` + +De `name` parameter is **nog steeds vereist** (niet *optioneel*) omdat het geen standaardwaarde heeft. Toch accepteert `name` `None` als waarde: + +```Python +say_hi(name=None) # Dit werkt, None is geldig 🎉 +``` + +Het goede nieuws is dat als je eenmaal Python 3.10 gebruikt, je je daar geen zorgen meer over hoeft te maken, omdat je dan gewoon `|` kunt gebruiken om unions van types te definiëren: + +```Python hl_lines="1 4" +{!../../../docs_src/python_types/tutorial009c_py310.py!} +``` + +Dan hoef je je geen zorgen te maken over namen als `Optional` en `Union`. 😎 + +#### Generieke typen + +De types die typeparameters in vierkante haakjes gebruiken, worden **Generieke types** of **Generics** genoemd, bijvoorbeeld: + +//// tab | Python 3.10+ + +Je kunt dezelfde ingebouwde types gebruiken als generics (met vierkante haakjes en types erin): + +* `list` +* `tuple` +* `set` +* `dict` + +Hetzelfde als bij Python 3.8, uit de `typing`-module: + +* `Union` +* `Optional` (hetzelfde als bij Python 3.8) +* ...en anderen. + +In Python 3.10 kun je , als alternatief voor de generieke `Union` en `Optional`, de verticale lijn (`|`) gebruiken om unions van typen te voorzien, dat is veel beter en eenvoudiger. + +//// + +//// tab | Python 3.9+ + +Je kunt dezelfde ingebouwde types gebruiken als generieke types (met vierkante haakjes en types erin): + +* `list` +* `tuple` +* `set` +* `dict` + +En hetzelfde als met Python 3.8, vanuit de `typing`-module: + +* `Union` +* `Optional` +* ...en anderen. + +//// + +//// tab | Python 3.8+ + +* `List` +* `Tuple` +* `Set` +* `Dict` +* `Union` +* `Optional` +* ...en anderen. + +//// + +### Klassen als types + +Je kunt een klasse ook declareren als het type van een variabele. + +Stel dat je een klasse `Person` hebt, met een naam: + +```Python hl_lines="1-3" +{!../../../docs_src/python_types/tutorial010.py!} +``` + +Vervolgens kun je een variabele van het type `Persoon` declareren: + +```Python hl_lines="6" +{!../../../docs_src/python_types/tutorial010.py!} +``` + +Dan krijg je ook nog eens volledige editorondersteuning: + + + +Merk op dat dit betekent dat "`one_person` een **instantie** is van de klasse `Person`". + +Dit betekent niet dat `one_person` de **klasse** is met de naam `Person`. + +## Pydantic modellen + +Pydantic is een Python-pakket voor het uitvoeren van datavalidatie. + +Je declareert de "vorm" van de data als klassen met attributen. + +Elk attribuut heeft een type. + +Vervolgens maak je een instantie van die klasse met een aantal waarden en het valideert de waarden, converteert ze naar het juiste type (als dat het geval is) en geeft je een object met alle data terug. + +Daarnaast krijg je volledige editorondersteuning met dat resulterende object. + +Een voorbeeld uit de officiële Pydantic-documentatie: + +//// tab | Python 3.10+ + +```Python +{!> ../../../docs_src/python_types/tutorial011_py310.py!} +``` + +//// + +//// tab | Python 3.9+ + +```Python +{!> ../../../docs_src/python_types/tutorial011_py39.py!} +``` + +//// + +//// tab | Python 3.8+ + +```Python +{!> ../../../docs_src/python_types/tutorial011.py!} +``` + +//// + +/// info + +Om meer te leren over Pydantic, bekijk de documentatie. + +/// + +**FastAPI** is volledig gebaseerd op Pydantic. + +Je zult veel meer van dit alles in de praktijk zien in de [Tutorial - Gebruikershandleiding](tutorial/index.md){.internal-link target=_blank}. + +/// tip + +Pydantic heeft een speciaal gedrag wanneer je `Optional` of `Union[EenType, None]` gebruikt zonder een standaardwaarde, je kunt er meer over lezen in de Pydantic-documentatie over Verplichte optionele velden. + +/// + +## Type Hints met Metadata Annotaties + +Python heeft ook een functie waarmee je **extra metadata** in deze type hints kunt toevoegen met behulp van `Annotated`. + +//// tab | Python 3.9+ + +In Python 3.9 is `Annotated` onderdeel van de standaardpakket, dus je kunt het importeren vanuit `typing`. + +```Python hl_lines="1 4" +{!> ../../../docs_src/python_types/tutorial013_py39.py!} +``` + +//// + +//// tab | Python 3.8+ + +In versies lager dan Python 3.9 importeer je `Annotated` vanuit `typing_extensions`. + +Het wordt al geïnstalleerd met **FastAPI**. + +```Python hl_lines="1 4" +{!> ../../../docs_src/python_types/tutorial013.py!} +``` + +//// + +Python zelf doet niets met deze `Annotated` en voor editors en andere hulpmiddelen is het type nog steeds een `str`. + +Maar je kunt deze ruimte in `Annotated` gebruiken om **FastAPI** te voorzien van extra metadata over hoe je wilt dat je applicatie zich gedraagt. + +Het belangrijkste om te onthouden is dat **de eerste *typeparameter*** die je doorgeeft aan `Annotated` het **werkelijke type** is. De rest is gewoon metadata voor andere hulpmiddelen. + +Voor nu hoef je alleen te weten dat `Annotated` bestaat en dat het standaard Python is. 😎 + +Later zul je zien hoe **krachtig** het kan zijn. + +/// tip + +Het feit dat dit **standaard Python** is, betekent dat je nog steeds de **best mogelijke ontwikkelaarservaring** krijgt in je editor, met de hulpmiddelen die je gebruikt om je code te analyseren en te refactoren, enz. ✨ + +Daarnaast betekent het ook dat je code zeer verenigbaar zal zijn met veel andere Python-hulpmiddelen en -pakketten. 🚀 + +/// + +## Type hints in **FastAPI** + +**FastAPI** maakt gebruik van type hints om verschillende dingen te doen. + +Met **FastAPI** declareer je parameters met type hints en krijg je: + +* **Editor ondersteuning**. +* **Type checks**. + +...en **FastAPI** gebruikt dezelfde declaraties om: + +* **Vereisten te definïeren **: van request pad parameters, query parameters, headers, bodies, dependencies, enz. +* **Data te converteren**: van de request naar het vereiste type. +* **Data te valideren**: afkomstig van elke request: + * **Automatische foutmeldingen** te genereren die naar de client worden geretourneerd wanneer de data ongeldig is. +* De API met OpenAPI te **documenteren**: + * die vervolgens wordt gebruikt door de automatische interactieve documentatie gebruikersinterfaces. + +Dit klinkt misschien allemaal abstract.
