For anyone afraid to jump around from one programming language to another, I think this video may help lay some of that fear to rest.

Another video I think is good for introducing Python to those familiar with other programming languages like javascript/json and C languages, and/or Ruby. I think this again shows that it is not as scary as it may sound to jump into Python.

An added note is that Cisco has a DevNet community for learning network programmability, and it has cloud development and network learning environments that are free (one at a time), but they do require downloading of an application to VPN into the online learning environments (sandboxes). I love this for the closer-to-more-of-an-anywhere-ability-to-work-on-these (I say “closer” because of this application that has to be downloaded, ie have to have my Mac lap rather than my chromebook.
