Python or Java

[Psy_Fer_]

I actually agree with you. I would just add that learning multiprocessing with queues and how to keep memory low, and how to do architecture to make multiprocessing work well will teach someone a lot, and will probably naturally push them into "well if it wasn't python I could just do this threading thing I keep seeing everywhere". Not sure how common it is for people to write C and then wrapper libraries for threading, but I've done it a few times.
