Should upgrade to Python 3.x
Most pages don't work with Python 3.x (v3.7 in my case). Reason is mostly that print is now a function and not a statement anymore, plus a few other subtle differences (standard functions that have been moved or removed etc.). Not sure, whether it's possible to create a version that runs under both Python versions, but upgrading this tutorial such that it runs under the newer seems desirable.
Thank you for opening this issue. Actually, all of the examples included in this book version works only with Python 2.x (it is an old book).
There is a Python 3.x version of this book but it is only a printed version and it was written in Brazilian Portuguese.
When the editor rights expire, maybe we'll publish this book online.
