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

Change your loop to strip white spaces from the top AND bottom of the output (notice extra "-" at the for loop close):

 {% for key, value in querystring.items() -%}
      {{ key }}: '{{ value }}'
 {%- endfor %}

In my tests (using https://github.com/abourguignon/jinja2-live-parser), the "-" must come after the first {%, not before the last to achieve what you're asking for.
