Jinja2 iterate over strings and lists

[Quentin Aveno]

Hi guys,
I got a question concerning list of lists and strings.

I have something like :
- name: test
vars:
test1: "test1"
test2:
- "test21"
- "test22"
test3:
- "{{ test1 }}"
- "{{ test2 }}"

debug:
msg: "{% for tt in test3 %} {{ tt }} {% endfor %}"

Is there a way to flatten the list into à list of strings with a filter ?

Use filter "flatten". For example

- debug:
msg: "{{ test3|flatten }}"

should give

"msg": [
"test1",
"test21",
"test22"
]
