Ansible join list items into string including the quotation marks

this is probably easy but i cant figure it out

I have a simple list which i need to convert to string but i need each item in the final string to contain quotation marks

vars:
  servers:
    - ServerA
    - ServerB
    - ServerC

tasks:
  - name: Join into string
    debug:
      msg: "{{ servers | join(,) }}"

result looks like this
   "msg": "ServerA,ServerB,ServerC"

but i need to get the format

msg: '"ServerA","ServerB","ServerC"'

Solution

Join the items

  result: >-
    "{{ servers|join('","') }}"

The debug

    - debug:
        msg: "{{ result }}"

gives the expected result

 msg: '"ServerA","ServerB","ServerC"'

You can write it into a file

  - copy:
      dest: /tmp/result.txt
      content: >
        "{{ servers|join('","') }}"

gives

shell> cat /tmp/result.txt 
"ServerA","ServerB","ServerC"

^{Example of a complete playbook for testing
- hosts: localhost

vars:

servers:
- ServerA
- ServerB
- ServerC

result: >-
"{{ servers|join('","') }}"

tasks:

- debug:
msg: "{{ result }}"
- copy:
dest: /tmp/result.txt
content: >
"{{ servers|join('","') }}"}
