How to pass a long list a variables to a script, comma seperated in double quotes ?

Hi All.

I currently pass a comma seperated list of variables to my ansible tower template in this matter

param1: xxxxx
server_port_list: “‘server1,4455’,‘server2,7777’,‘server3,5588’”

I have a file which has the contents below.

server1,4455
server2,7777
server3,5588

I have written the playbook in such a way that I now have access to the file.

I use the snippet below to read the file content.

  • name: read file content
    win_shell: type {{server_list}}
    register: my_server_list

I need it passed to my script in this format, “‘server1,4455’,‘server2,7777’,‘server3,5588’”

How can i do this in ansible ?
