jinja2 how to remove trailing newline
I think you can get rid of it using the whitespace control feature. Thus I would modify the endfor
block to {% endfor -%}
See if that does it!
For those using Flask who arrive here, these lines did the trick for me:
app = Flask(__name__)
app.jinja_env.lstrip_blocks = True
app.jinja_env.trim_blocks = True
Change your loop to strip whitespace 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.
