The big difference is unicode; Python3's distinction between
str and bytes and bytearrays is The Best Way to handle unicode,
and I hope all future languages will borrow it.
"Py3 builds on the years of experience with Py2 and omits some
of its misfeatures". For example, in Py3 5/2 is 2.5, whereas in
Py2 5/2 is 2 but 5/2.0 is 2.5, lots of other stuff.  Search for:
  Moving from Python 2 to Python 3

I've been writing Python for years, and I've never used Python2.
It's frozen.  IMHO, I recommend you start with Python3.

But, as you can tell, opinions differ on this point :-)

Also, apologies for the off-topic-ness...
