> * If I make some claim during class that is not accurate, the students - who, again, are all professional engineers in the work force - will eat me alive.

This is interesting. I imagine that in high-level training for any industry this could happen. I'd personally try to let my students know that I'm not an all-knowing god and ask them to correct me if they noticed something I said was wrong, and I'd be happy learning something new. Maybe this is what you meant, but were you ever met with hostility or animosity because of this?

Also, what, in general, is intermediate-to-advanced Python?
