These features are what Marshmallow was built to provide. It is a great library, and I have used it a lot before.

But it was created before there existed Python type hints. So, to define every <abbr title="the definition of how data should be formed">schema</abbr> you need to use specific utils and classes provided by Marshmallow.

### Limitations

C'est un programme très simple.

Mais maintenant imaginez que vous l'écriviez de zéro.

À un certain point vous auriez commencé la définition de la fonction, vous aviez les paramètres prêts.

Mais vous aviez besoin de "cette méthode qui convertit la première lettre en majuscule".

Était-ce `upper` ? `uppercase` ? `first_uppercase` ? `capitalize` ?

### Bearbeiten Sie es

Es ist ein sehr einfaches Programm.

Aber nun stellen Sie sich vor, Sie würden es selbst schreiben.

Irgendwann sind die Funktions-Parameter fertig, Sie starten mit der Definition des Körpers ...

Aber dann müssen Sie „diese Methode aufrufen, die den ersten Buchstaben in Großbuchstaben umwandelt“.

War es `upper`? War es `uppercase`? `first_uppercase`? `capitalize`?
