Do I need to learn python 2 before 3?
Why you should learn Python 2 Very soon there will be no future security or bug fixes for Python 2. x, and your time is better spent learning 3. x. In the unlikely event that you end up working with a legacy Python 2 code base, tools like python-future will make it easy for you to use having only learned Python 3.
What version of python do I have on Raspberry Pi?

If I double click on a .py file it opens “IDLE” (is there another way to open “IDLE”?), but the default python version is 2 when I select “run”. I want to PERMANENTLY change the default version to 3 so that I don’t have to switch versions every time I switch on my Raspberry Pi.
Why is Python 2.x incompatible with Python 3?
