Getting array keys in Twig? (Symfony)

Is it possible to get the key of an array in Twig (in Symfony)?

For example if I have an array of:

array(
'key1' => 'value1',
'key2' => 'value2',
);

Is it possible in Twig to print:

key1: value1

key2: value2

Thanks

Try following format:

{% for key, value in array %}
    {{ key }} - {{ value }}
{% 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>

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

{% set keys = array|keys %}

or

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