I tried that also...but got error:
fatal: [host1]: FAILED! => {"failed": true, "msg": "the field 'args' has an
invalid value, which appears to include a variable that is undefined. The
error was: 'i' is undefined\n\nThe error appears to have been in
'/etc/ansible/template_jinja_eval2.yml': line 11, column 7, but may\nbe
elsewhere in the file depending on the exact syntax problem.\n\nThe
offending line appears to be:\n\n tasks:\n - name: Printing message\n
^ here\n"}
