jinja2 how to remove trailing newline

Question

I\'m using jinja 2 to output a yaml file but can\'t seem to get rid of a trailing newline and the end of a for loop. Eg the below

 - request:
        path: {{ p

The accepted answer is only half of the solution, because it removes all newlines.

You can avoid the trailing newline by first removing all newlines (using the minus signs at -%} and {%- in the for loop), and then inserting the desired newlines at the right place (using the loop.last condition).

The following templates renders a dictionary, d, to as JSON text:

{
    {% for key, value in d.items() -%}
    "{{ key }}": "{{ value }}"{{ ",
    " if not loop.last }}
    {%- endfor %}
}

For d = {'a':'1', 'b':'2'}, the template renders to

{
    "a": "1",
    "b": "2"
}
