The book "A Byte of Python" talks about the third version of Python?

Question

Python

Instead of reading it yourself, well, at least here:

This book describes the Python 3 language, despite the fact that Python 2 is all even more common is
to go to the forum, ask a question, wait for an answer that may not be reliable, then believe this answer and with a sense of pride and greatness go to ask the next question, instead of trying to solve it yourself.
Who can explain the train of thought of the questioner? Is this the next generation of "IT professionals"?
