Someone wanting to learn Python (or any other language) will be better served if they are helped to focus at most important and least painful things first: in this case, python 2 is everywhere with huge number of libraries. Whatever you need is 'pip install' away.
Learning Python 2 is not a waste of time: whatever you learn and is changed in Python 3, will be easily relearned once it becomes needed.
