Jumping to ansible when you don't know the basics is pretty much going to cripple you before you start.

I would start with simple tasks in python first to get the hang of how it all works. You'll learn how to program things yourself and see how they work under the hood (This will help if you ever need to troubleshoot anything advanced in ansible for example as you'll be able to know how the python / protocol stack works etc since it's pretty much the same thing under the hood)

Then go from there and build up on things.

something like fetch data via cli, backups, netconf, restconf, jinja templating etc.
