Is it possible to learn Python 3 from Python 2 tutorials?

Question

Python

I started learning Python using the well-known A Byte of Python, which describes the 3rd branch of Python.
I was looking for additional assignments/materials and came across a suggestion to try the Google course on python and the book Learn Python the Hard Way . But they rely on the 2nd version.
Isn't it harmful to use these manuals in this case? Or, maybe, something else is written specifically for Python 3 that is just as well-known and suitable? I want to focus on the implementation of practical tasks (and it would be useful if the answers to the tasks were available for analysis).

Answer 1

Firstly, since they started to teach from some book - why change the material? If you are satisfied with "A Byte of Python", then calmly continue.
Secondly, there will be no problems specifically in training. Some serious differences between the 3rd and 2nd versions are too rarely used to be afraid (not counting the banal differences between strings and some kind of print). And if you stumble, then finding a solution is a matter of one minute.

Answer 2

Most books on the 3rd branch describe the differences from the 2nd, there are not so many of them.
I advise you to try your abilities in CheckiO, where you can solve tasks both on the second branch and on the third =)
