Zum Beispiel würde `list[int]` überprüfen (und dokumentieren), dass der Inhalt der Liste Ganzzahlen sind. Aber `list` alleine würde das nicht.

<h3 id="symbols">Symbols</h3>

<p>
Some symbols, such as <code>R1</code> or <code>LR</code>,
are predefined and refer to registers.
The exact set depends on the architecture.
</p>

<p>
There are four predeclared symbols that refer to pseudo-registers.
These are not real registers, but rather virtual registers maintained by
the toolchain, such as a frame pointer.
The set of pseudo-registers is the same for all architectures:

#### List { #list }

Por exemplo, vamos definir uma variável para ser uma `list` de `str`.

Declare a variável, com a mesma sintaxe com dois pontos (`:`).

Como o tipo, coloque `list`.

Como a lista é um tipo que contém tipos internos, você os coloca entre colchetes:

     *
     * Unfortunately, we don't distinguish between these two cases in our public API: Joiner.on(...)
     * and Joiner.on(...).useForNull(...) both declare the same return type: plain Joiner. To ensure
     * that users *can* pass null arguments to Joiner, we annotate it as if it always tolerates null
     * inputs, rather than as if it never tolerates them.
     *

* Vérifier qu'il existe un paramètre de requête facultatif nommé `q` (comme dans `http://127.0.0.1:8000/items/foo?q=somequery`) pour les requêtes `GET`.
    * Puisque le paramètre `q` est déclaré avec `= None`, il est facultatif.
    * Sans le `None`, il serait nécessaire (comme l'est <abbr title="en anglais : body">le corps</abbr> de la requête dans le cas du `PUT`).
