[Tutor] Python 2 vs Python 3

[vrkratheesh at live.com]

Hi I am starting to learn Python with the help of head first python. I have installed python 2.x.x.  But the book is explaining python 3 syntaxes. For example,  

Avoiding a new line in print statement which made a confusion to me.  So is it wise I change to python or can anyone recommend any websites or books where I can see the difference between python 3 and python 2 syntax changes.  Thanks in advance.
