You can use the keys filter. The keys filter returns the keys of an array.

{% set keys = array|keys %}

{% for key in array|keys %}   {{ key }}{% endfor %}

If you have this array: person = ['name': 'John', 'age': '30'], you can display the value of a specific key, like this:

<p> Name = {{ person.name}} </p><p> Age= {{ person.age}} </p>
