You're still top-posting.  Put your response either directly after the 
part you're responding to, or at the end.  And of course, trim out the 
irrelevant parts (which I've been frequently criticized for failing to do)

I'm sorry, but I don't understand the phrase "the significance of each 
version".

Python 3 changed  a number of things to try to bring symmetry to the 
language and the libraries.  The most significant changes were the print 
statement and unicode, but there were a number of other changes, and I 
don't know all the rationales.  In this case, the naming convention for 
modules is all lower-case, and the naming convention for classes is a 
leading capital.

I usually advise people that are using Python 2.x to avoid using 
training materials oriented towards Python 3, as these confusions happen 
pretty often.
