I'm new in programming. I just want to know if it would be too hard or complicated to use Python 2.7 with the Python for Kids book? I am still practicing for a class I took with v 2.7. Can I have both IDLE 2.7 and 3 in the system and use them separately and not run into problems? Thank you.

Most of the examples in the book will work with Python 2.7 -- but some won't without modification (particularly anything using the tkinter module). And you may hit subtle problems which will be harder to figure out as a consequence. However, you can install both Python 2.7 and 3 on the same system (you didn't say, but I'm guessing you're using Windows -- after installation, you'll find you've got both c:\Python27 and c:\Python34 directories, assuming you install the latest Python version, on your hard drive) -- just make sure you select the correct directory when setting up the IDLE shortcut (described in Chapter 1).
