How to display a list in flask without brackets? (by using jinja2 batch)

I am trying to display a list in flask where every two items of a list are printed on a new row.

{% for x in sources| batch(2) %}
    <h2>{{ sources}} </h2>
    {% endfor %}

This works, but the items are displayed with brackets and quotes e.g. ['rain', 8.0]. I want to display them like rain : 8.0 How do i get rid of those brackets and quotes?

Edit: The sources list is: ['Decibel', 5, 'People', 3, 'Temperature', 2, 'Rain', 8, 'Time', 21]. I want to display it as Decibel, 5 and then on the next row People, 3 etc.

I also tried 

  {% for x in range(0, sources|length,2) %}
    <h2>{{ sources[x],sources[x+1] }} </h2>
    {% endfor %}

but then the quotes and brackets are also displayed.

This code below does not print the brackets and quotes, but only displays one item per row.

{% for x in sources %} <h2>{{ x }} </h2> {% endfor %}

If you only use 2 elements

<h2> {{ x[0] }}: {{ x[1] }} </h2>

Or you can use:

{{ x|join(':') }}

it looks like the python join
