You said, "However the split happens based on ',' , and then we remove
the quotes with map('map', 'trim')) and align the lines with range."
It's true that "split(',')" will split a string containing commas into a
list of strings. But the trim filter does nothing with quotes.
Rather, "trim" removes leading and trailing spaces from the string piped
into it:
a_string | trim
Further, "map('trim')" removes leading and trailing spaces from each
string of the list of strings passed to it:
[str0, str1, str2] | map('trim')
Finally, "map('map', 'trim')" trims strings two levels deep in lists:
[[sa0, sa1], [sb0, bs1], [sc0, sc1]] | map('map', 'trim')
Quotes never play into it. In fact, in what you initially posted, and in
my response, the string data contain no quotes.
Also, "range" isn't to align anything. It provides the necessary first
parameter to the "extract" filter.
However assuming split with delimiter as comma, when i try to replace
1 with 0 the output is [msg: "{{ range(my_var | length) |
map('extract', (my_var | map('split', ',') | map('map', 'trim')),
[*0*]) }}"]
Yes, you changed the "1" to a "0", so you get the first (index=0) item
in the list produced by the split.
When it was "1", you got the second item (index=1) in each list produced
by the split, that is "color-red", "color-blue", and "color-orange".
From your initial post, that's what I thought you wanted.
If what you really want is this:
new_var:
- line1 has color-red
- line2 has color-blue
- line3 has color-orange
then you can use this instead:
- name: First and Second parts from split on comma
ansible.builtin.set_fact:
new_var: "{{ my_var | map('regex_replace', '^([^,]*),([^,]*),.*', '\\1 \\2')
| map('regex_replace', ' +', ' ') }}"

1 with 0 the output is [msg: "{{ range(my_var | length) |

}}"]
ok: [localhost] =>
msg:
- line1 has
- line2 has
- line3 has
and when tried to add [0 1] in the end [msg: "{{ range(my_var |
length) | map('extract', (my_var | map('split', ',') | map('map',
'trim')), [0 1]) }}"]
it printsok: [localhost] =>
msg:
- i
- i
- i
that is second character in the word line[0]. Is not the split breaks
the words with (',')?
How to print all the available column? instead of 1( yes the full
file without a comma now )
Actually I am trying to print like below
line1 has color-red
line2 has color-blue
line3 has color-orange

In the code below, note that "range(my_var | length)" is

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 ??
