问题描述
我只想遍历现有列表，并用逗号分隔字符串.
像这样:my_string = 'stuff, stuff, stuff, stuff'
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'
我已经了解了loop.last，我只需要知道如何在我的代码下将第三行写到WORK.
I already know about loop.last, I just need to know how to make the third line in my code below WORK.
{% set my_string = '' %}
{% for stuff in stuffs %}
{% set my_string = my_string + stuff + ', '%}
{% endfor%}
推荐答案
如果stuffs是字符串列表，则可以使用:
If stuffs is a list of strings, just this would work:
{{ stuffs|join(", ") }}
