En faisant cela, votre éditeur pourra vous aider, même pendant que vous traitez des éléments de la liste.

Sans types, c'est presque impossible à réaliser.

Vous remarquerez que la variable `item` n'est qu'un des éléments de la list `items`.

Et pourtant, l'éditeur sait qu'elle est de type `str` et pourra donc vous aider à l'utiliser.

#### `Tuple` et `Set`

Tout le framework **FastAPI** a été conçu avec cela en tête. L'autocomplétion fonctionne partout.

Vous devrez rarement revenir à la documentation.

Voici comment votre éditeur peut vous aider:

	// Otherwise same set of buckets get scanned across erasure sets always.
	// at any given point in time. This allows different buckets to be scanned
	// in different order per erasure set, this wider spread is needed when
	// there are lots of buckets with different order of objects in them.
	r := rand.New(rand.NewSource(time.Now().UnixNano()))
	permutes := r.Perm(len(buckets))
	// Add new buckets first

Sonunda senin sıran, aşkın 😍 ve kendin için 2 hamburger 🍔 siparişi verdiniz.

Ödemeyi yaptınız 💸.

Kasiyer mutfağa gider 👨‍🍳.

Sırada bekliyorsunuz 🕙, kimse sizin burgerinizi 🍔 almaya çalışmıyor çünkü sıra sizin.

Sen ve aşkın 😍 sıranızı korumak ve hamburgerleri almakla o kadar meşgulsünüz ki birbirinize vakit 🕙 ayıramıyorsunuz 😞.

C'est ainsi que cela fonctionne dans Flask, Starlette, Responder, etc.

Mais alors, nous avons à nouveau le problème d'avoir une micro-syntaxe, dans une docstring Python (un gros morceau de YAML).

L'éditeur ne peut guère aider en la matière. Et si nous modifions les paramètres ou les schémas Marshmallow et que nous oublions de modifier également cette docstring YAML, le schéma généré deviendrait obsolète.

many teeth, so she felt that it ought to be treated with respect.

  `Cheshire Puss,' she began, rather timidly, as she did not at
all know whether it would like the name:  however, it only
grinned a little wider.  `Come, it's pleased so far,' thought
Alice, and she went on.  `Would you tell me, please, which way I
ought to go from here?'

  `That depends a good deal on where you want to get to,' said
the Cat.
