...ANSWER
Answered 2020-Oct-07 at 16:07Looking in the nornir module docs there is no print_result function, but it is present in the nornir_utils module.
The plugins present in nornir are four, look here
You can install the nornir_utils module with pip install nornir_utils and the nornir module as pip install nornir.
The corrent import to do is from nornir_utils.plugins.functions import print_result.
Make sure to use the right pip to install the packages, sometimes I install in the wrong env having multiple python installation.

Answered 2019-Nov-13 at 19:33If you trace the code of nornir.core.task.run you'll find that it simply passes the keyword arguments down to the plugins, eventually to t.render in nornir.core.helpers.jinja_helper.render_from_file.
You can therefore simply pass your function object as an additional keyword argument to task.run to make it available in the namespace of the template:
