When you add the extention "_parallel" to the RUN statement will nornir handle the multiple tasks at the same time. That is especially usefull in the config-archive script. In full my comment:
replace this line " r = task.run(task=netmiko_send_command, command_string=cmd)"
with this line "r = task.run_parallel(task=netmiko_send_command, command_string=cmd)"
Where "_parallel" will show what it will do. Try it and you will find nornir will be extreme fast in parallel modus.

Hey John.

is there any other way not to hardcode username and password in hosts file ? I mean, like using getpass ?

Hi John! Thank you very much for this script :) This video combined with some of your past ones gives me a better understanding of options available to me. All I got to do is start playing with Python :)
If I can make a suggestion for a future video, it would be great to see how you build a script which for example converts a .csv or a .xls file inventory file to hosts.yaml.
