String concatenation in Jinja

Question

I just want to loop through an existing list and make a comma delimited string out of it.
Something like this: my_string = \'stuff, stuff, stuff, stuff\'

Answer 1

You can use + if you know all the values are strings. Jinja also provides the ~ operator, which will ensure all values are converted to string first.

{% set my_string = my_string ~ stuff ~ ', '%}
