What is the best way to import the synchronized queue class that is

This seems somewhat unpythonic. Is there a better way without

Next, I introduced the concept of

I teach Python at two colleges in Silicon Valley. I currently teach an
introductory course on Python and most of my students have no programming
background whatsoever. Up until now, my colleges have been using Python 2.
But now, one of the colleges has made the jump to Python 3. So I am upda

Back in the old days, it was possible to raise strings instead of the
