No, you should not worry about it.
My entire career, doing full-out conversions from python 2 to python 3 I've
run into only two problems.
1) In python 3, you need to output stuff via a print() as opposed to a
print "" in python 2
2) python 3 defaults all character encodings to unicode, whereas python 2
needed a unicode string specified with a u''
by python 3.4, they made it so the u'' syntax is ignored and just made into
a string.
Often, to get python3, it's a package named python3
Also, everything I've seen from the head-first series is basically just
fluff where the authors care more about hearing themselves talk than they
do about covering the subject matter.
Honestly, getting ipython/bpython installed and just tab-completing
everything and using the built-in documentation is as good as any textbook,
but starting out that way is kinda difficult.
