In the code below, note that "range(my_var | length)" is equivalent to
"[0, 1, 2]".
In the set_fact, we don't "loop" the task; rather we loop over the data
within the jinja2 expression by using the map filter.

I want to use the output lines as an input for another variable using
set_fact , as like below .
- name: Filtering the color data
ansible.builtin.set_fact:
new_var: "{{ item.split(',')[1] }}"
loop: "{{ var1 }}"
and I am looking for the data like below
color-red
color-blue
color-orange
- debug:
var: new_var
gives only color-red
But my var1 looping process the first line only in from the my_var
and not the next 2 lines.
This is an example and I may expect lines from my_var from 0 to 100's.
How to print the column[]of output) with multiple lines ??
