rise4fun z3py is unavailable from several weeks due to some security issues. I tried to find out some resources for learning z3py but ended in vain. Please suggest some resources to learn z3py

Answer 1

I created a zip file with the Z3Py tutorials sources. It is basically a few HTML pages and a bunch of python files. Here is the link:

Update (Jan 14, 2014): the Z3Py tutorials are back online
