# Dictionnaires dans les blocs de code

Dynamo 2.0 introduit non seulement les nœuds précédemment abordés dans les dictionnaires, mais aussi les blocs de code.

Vous pouvez utiliser une syntaxe semblable à celle présentée ci-dessous ou des représentations de nœuds basées sur DesignScript.

Étant donné qu’un dictionnaire est un type d’objet dans Dynamo, nous pouvons lui appliquer les actions suivantes.

La gestion de ce type d’interactions est particulièrement utile lorsque vous associez des données Revit à des chaînes. Nous allons maintenant examiner certains cas d'utilisation de Revit.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://primer2.dynamobim.org/fr/5_essential_nodes_and_concepts/5-5_dictionaries-in-dynamo/3-code-block-uses.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
