What does this "-" in jinja2 template engine do?
15,705
It suppresses extra vertical spacing, commonly used when you don't want excessive spacing between elements you're looping through.
If you put an minus sign (-) to the start or end of a block (for example a for tag), a comment or variable expression you can remove the whitespaces after or before that block

I am learning jinja2 because Google App Engine recommends it.
I found this example on Wikipedia: http://en.wikipedia.org/wiki/Jinja_%28template_engine%29
{%- for item in item_list %} {{ item }}{% if not loop.last %},{% endif %} {%- endfor %}
What is the "-" in "{%- for"?
Also, where can I find jinja2 examples (better with Google App Engine)?
Thanks a lot!
