You can use with\_sequence or range in a for loop.

&nbsp;&nbsp;vars:  
&nbsp;&nbsp;&nbsp;&nbsp;myvar:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- one  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- two  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- three  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- four  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- five  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- six  
&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- debug: msg="{{ myvar[item | int] }},{{ myvar[item | int + 1] }},{{ myvar[item | int + 2] }}"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;with\_sequence: start=0 end={{ (myvar | length) - 1 }} stride=3

&nbsp;&nbsp;&nbsp;&nbsp;- debug:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: |  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{% for i in range(0, myvar | length, 3) %}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{{ myvar[i] }},{{ myvar[i + 1] }},{{ myvar[i + 2] }}  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{% endfor %}

Hi Sai Stian,

This syntax would be helpful but i may be using in wrong way as i am getting below errors. Please help on fixing the issue.

- name: debug with with sequence  
debug:  
msg:“{{ volchk[item.stdout | int] }},{{ volchk[item.stdout | int + 1] }},{{ volchk[item.stdout | int + 2] }}”  
with\_sequence: start=0 end={{ (volchk | length)-1 }} stride=3

**error:**

FAILED! =\> {“msg”: “The task includes an option with an undefined variable. The error was: ‘ansible.utils.unsafe\_proxy.AnsibleUnsafeBytes object’ has no attribute ‘stdout’\n\nThe error appears to be in ‘/suresh/suresh\_playbooks/nfsvolmigration/roles/mountcheck/tasks/volcheck.yml’: line 44, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n ignore\_errors: true\n - name: debug with with sequence\n ^ here\n”}

Debug “volchk.result” output:

Can you paste the content of “volchk” list … Also try using item.stdout\_lines instead of item.stdout in your debug task.

thanks Neha, Kai

I could fix the issue by using range with stdout.split(). Even, it is working with stdout\_lines as well

Once again thanks to all for helping me on this request.
