> The code you pasted used both spaces and tabs for indentation. The thing is that python, by default, interprets one tab character as 8 spaces, but the editor you've used shows it as 4 spaces. To avoid these kinds of headaches, I always 1) set my editor to show tabs, so I can detect them, and 2) never use tabs when I write code myself. I set my editor to insert 4 spaces whenever I hit the "tab" key on my keyboard. If you post the name of your editor, maybe someone knows how to do that in yours. You can also detect mixed space/tab issues by running "python -t" instead of just "python".

Of course, it's not a big deal learning python 3 if you know python 2 either, but why spend energy on it?
