The textbook that Barbara Ericson and I wrote uses Jython: https://www.amazon.com/Introduction-Computing-Programming-Python-4th/dp/0134025547.  Last I saw market analysis, it's the third most popular Python University textbook, at least in the US.  If you read the reviews for the book, you'll see that lots of people are confused about Jython vs. Python.  Quoting one:

So I'll just ask the obvious: CPython and Jython are supposed to be 
alternative implementations of the same language, Python.  IronPython is 
another.  How does a different implementation imply a different language?
