I am going through the book mentioned in the subject line, and I have found a
couple of things that don't seem to work the way the author shows in the book.
So, either I am doing something wrong, or what he is saying isn't quite right.
I am using Python 2.7.1 on Mac OS X Leopard.

That is correct about the difference between Python 2 and Python 3 syntax.
However, I am surprised that with 2.7.1 these do not work. I have found
that on my Ubuntu system with Python 2.6.5 these Python 3 syntax items do
seem to work properly. I am assuming they were back ported or something.

Bill,
Try this:
print(hello, Bill)
('Hello', 'Bill')
x = input(Your name?)
Your name?Bill
Traceback (most recent call last):

Quite right! I see what you mean. I quite inadvertently stumbled into
examples that would work without realizing it. I typically program in
Python 3, so not as familiar with the limitations on Python 2x. I've had
quite a chuckle over this!
Thanks,

input() must be avoided at all costs in Python 2.x. if you find any
Python (2.x) book which employs that, consider the author uninformed.
it is a huge security risk and the main reason why in Python 3
raw_input() is renamed to and replaces input().
