# \[] (access)

### Description

To access an the value of an entry in a dictionary use the `A_DICTIONARY[KEY]`, where `KEY` is the key of the entries which's value you would like to access.

### Examples

```
{"Id": 7, "Color": "red"}["Id"]
```

This creates a dictionary with two entries, we access the value of the entry with key `"Id"` and return therefore `7`.

{% hint style="info" %}
If you access an element that does not exist your rule will fail. You can check if a certain entry is present with the `in` operator, e.g.\
\
`If "Id" in p.values then`\
`p.values["Id"]`\
`else`\
`"Contract has no Id"`\
`end`
{% endhint %}
