Hi Joe (sorry for delay, I took the weekend off. BTW, on a totally different note, why is the date showing March 29 on last reply??),
Yes, you're absolutely right, it's a Python version thing. I started my session in Python 3.x and so the examples in the web2py book weren't working as it seems they're based off Python 2.x (I was getting: > SyntaxError: invalid syntax. My question is how to update the book so that super noobs like me won't trip over the same thing. It would just need a line mentioning that in Python 3, you'd have to do it 'X' way (and how to check which version you're using). Or something like that. Would we try a pull request to try an update or just mention in this space and someone will attend to it?
