Power splah'

I'm running my credit card close to the edge (my definition = barely enough in the checking account to pay it off) but payday is tomorrow, I have several projects to work on, and I've had it with the cheap bench power supply that I have. I went ahead and ordered the Korad programmable bench supply. At least I will be able to set a voltage properly. The USB interface seems interesting. Writing an interface for it might be a cool reason to learn Python or something.
There's a ton of work being done in Python in the embedded and scientific data gathering and analysis world. I hear Python more than any other language when I listen to embedded systems podcasts.

A lot of the 3D printing utilities are written in Python. I've heard more than one guest on say that they think Python would be a good first language to teach people.

I tend to agree with the most recent Embedded guest though - it doesn't matter what language you teach first; anyone who "gets" programming will learn whatever language they need once they get started.
Back in the dark ages, when I created my own PDP-11 to Nicolet digital scope interfaces on wirewrap boards, Python didn't exist...

Python would clearly make an excellent and more maintainable interface language.

Having said all that: I have to wonder what the best first language would be. Not Basic, obviously; not Python with its archaic "format by indentation"; I'd have to go with Javascript at the moment as being both highly interactive and easy to use, and very useful.
Javascript is certainly a valid choice and is being taught as an introductory language. The advent of node.js has made it a much more valid general purpose language.
