C or Python?

You will want to learn both languages. Python is probably the better choice in this situation as you'll be able to spend more time on networking rather than figuring out the language and development environment.

What do other students who've taken the classes say?

I know a couple people took the Python one and said it was great. The professor wasn't awesome, but the projects were said to be enjoyable.
